Question

. Find the zeroes of the given quadratic polynomials and verify the relationship between the zeroes and
coefficients. X2 - 2x -8​

Answer 1

Explanation:

$x {}^{2} - 2x - 8 = x {}^{2} - 4x + 2x - 8 \\ = x(x - 4) + 2(x - 4) \\ = (x - 4)(x + 2)$

x-4=0

x=4

x+2=0

x=-2

The zeroes are 4and -2
