Question

Find the zeroes of the polynomial f(x) = 4x² + 8x and verify the relationship between the zeroes and its coefficients.

​

Answer 1

Answer:

Given polynomial can be written as 4x

2

+8x=4x(x+2)=0

Hence the roots are x=0,x=−2

The sum of roots are

a

−b

=−2

and the product of roots are

a

c

=0
