Question

if one of the zeros of the quadratic polynomial F(X) = 4x square minus8 K X + 8 x minus 9 is the negative of the other then find the zeros of the kx square minus 3kx + 2

Answer 1

4x^2-8x(k+1)-8=0
for some value of x
it's given that one root is negative of other
then
8(k+1)/4=0
k=-1
-x^2+3x+2=0
=>x=2or1(factorize)
