# What is two root of an equation?

Two roots of an equation refer to the two values of the unknown variable that satisfy the equation and make it true.

## So let us dig a little deeper

Two roots of an equation refer to the two values of the unknown variable that satisfy the equation and make it true. As Aristotle once said, “The roots of education are bitter, but the fruit is sweet.” In the world of mathematics, understanding the concept of roots is crucial in solving equations and real-life problems. Here are some interesting facts on the topic:

• An equation can have 0, 1, 2 or more roots, depending on its degree and coefficients.
• The roots of a quadratic equation (ax^2 + bx + c = 0) are given by the formula: (-b ± √(b^2 – 4ac)) / 2a.
• If the discriminant (b^2 – 4ac) of a quadratic equation is negative, then the roots are imaginary.
• A cubic equation (ax^3 + bx^2 + cx + d = 0) can have either 1 real root and 2 imaginary roots or 3 real roots.
• The roots of a polynomial equation (anxn + an-1xn-1 ++ a1x + a0 = 0) can be found using methods such as factoring, synthetic division and the Rational Root Theorem.

To better visualize the concept of roots, here is a table showing the roots of some basic equations:

Equation Roots
x^2 – 4 = 0 -2, 2
5x + 10 = 0 -2
2x^2 + 5x + 3 = 0 -1, -3/2

In summary, roots are an important aspect of solving equations and understanding the behavior of mathematical functions. As we continue to learn and grow in our education, may we embrace the bitterness of the roots and enjoy the sweet fruit of knowledge.

The video explains how to find the roots of a quadratic equation, using an example that is not in the standard form. The equation is first converted into the standard form and then the values of `a`, `b`, and `c` are determined. The two numbers that add up to `-8` and multiply to `-9` are found, and the equation is factored into `(x – 9)(x + 1) = 0`. Finally, by setting each parenthesis equal to zero and solving for `x`, the roots of the equation are found.

The roots are calculated using the formula, x = (-b ± √ (b2 – 4ac) )/2a. Discriminant is, D = b2 – 4ac. If D > 0, then the equation has two real and distinct roots. If D < 0, the equation has two complex roots.

A quadratic equation has two roots or zeroes namely; Root1 and Root2.

A quadratic equation always has two roots, if complex roots are included; and a double root is counted for two.

The quadratic equation will always have two roots. The nature of roots may be either real or imaginary.

The inputs or values for the variables for which the equation gives 0 as the result are known as roots of the equation.

moreover we can write x^2+5x+6=(x+2)(x+3)=0

=%3E x+2=0 or x+3=0 ; so x=-2 or x=-3

for ex- x^2+5x+6=0 is an equation, then the only possible values of x are -2 and -3 for which the equation gives 0 result.

Additionally, How do you find the two roots of a function? The reply will be: The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Regarding this, When an equation has 2 equal roots?
The answer is: We know that quadratic equation has two equal roots only when the value of discriminant is equal to zero. We know that two roots of quadratic equation are equal only if discriminant is equal to zero. , we cannot have k =0.

Accordingly, How to solve √ 2?
The reply will be: √2 = 1.41421356237309504880168872420969807856967187537694…
For general use, its value is truncated and is used as 1.414 to make calculations easy. The fraction 99/70 is also sometimes used as the value of √2.

Considering this, What are the roots of an equation? The reply will be: The roots of an equation is a fancy way of saying "ssolutions" of the equation. Solutions are the numerical values equal to the variable after solving it. Roots can be found for any kind of equation, from linear to quadratic, to cubic, etc. There are two ways to find the roots of an equation: graphically or algebraically.

Simply so, How many roots can a quadratic equation have?
As a response to this: The roots of a quadratic function are the x-coordinates of the x-intercepts of the function. Since the degree of a quadratic equation is 2, it can have a maximum of 2 roots. We can find the roots of quadratic equations using different methods.
