Question

find the zeroes of the quadratic polynomial f(x)=x^2-2x-8, find the value of ab^2+a^2+b​

Answer 1

Answer:

given f(x)=x^2-2x-8

x^2-4x+2x-8=0

x(x-4) +2 (x-4) =0

(x-4) (x+2)=0

x-4=0,x+2=0

x=4,x=-2

the zeros of quadratic polynomial are 4,-2..

a=4

b=-2

ab^2+a^+b

4(-2)^2+(4)^2+(-2)

16+16-2

32-2=30
