Question

Find the zeroes of the polynomial 4x2 – 9 and verify the relation between the zeros and its coefficients.

Answer 1

Answer:

the zeroes are 3/2 and (-3/2)

Step-by-step explanation:

4x^2-9

=(2x)^2-3^2

=(2x+3)(2x-3)

therefore,

(2x+3)=0 or (2x-3)=0

=>x=(-3/2). =>x=3/2

now,

3/2+(-3/2)=3-3/2

=0

=-0/4

=-b/a

3/2×(-3/2)=-9/4

=c/a
