Question

If the zeroes of quadratic opolynomial ax^2 + bx + c, c#0
are equal then
​

Answer 1

Answer:

Given:

•   The zeros of the quadratic equation are equal

Prerequisite  Knowledge

• Quadratic Equation :  The equation of degree two is known as Quadratic equation.

• Quadratic Equation = $\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

Solving Question:

 we are given the zeros of the polynomial ax² + bx +c is equal

Thus, we can use the condition of this case

Solution:

          We know that ,if the zeros of the quadratic equation are equal then the determinant

⇒ b²-4ac = 0

The zeros are $\dfrac{-b}{2a}\:and\:\dfrac{-b}{2a}$

Answer 2

If its zeros are equal yhat means its descriminant is = o on solving this equaltion by b^2-4ac = o

then the two roots we will get will be equal in magnitute.

In this equation Ax^2+ bx + c =0

here the equal roots can be find by the shreedhar acheriya formula
