Question

.Find the zeroes of the given quadratic polynomials and verify the relation between the zeroes

and its coefficients

4x2-12​

Answer 1

Factorize the equation, we get (x+2)(x−4)

So, the value of x

2

−2x−8 is zero when x+2=0,x−4=0, i.e., when x=−2 or x=4.

Therefore, the zeros of x

2

−2x−8 are -2 and 4.

Now,

⇒Sum of zeroes =−2+4=2=−
