Question

find the zeroes of the quadratic polynomials and verify the relationships between the zeroes and the coefficients x2 -2x-8

Answer 1

x2-2x-8=x2-4x+2x-8=x(x-4)+2(x-4)=(x+2)(x-4).

x=-2 let s
-8x=4 let d
relation is x2-(s+d)x-sd
=x2-(2)x-8
=x2-2x

Answer 2

ok can u please refer ncert same problem is given in all in one also
