Question

Given g(x)=px+q where p and q are constants.If g^2(x)=16x+15 find the possible values of p and q?

Answer 1

I am confused by your data

if by g^2(x) you mean g(x)*g(x)
then it would be (px+q)^2
= p^2x^2 + 2pqx + q^2

but that was equal to 16x + 15
there was no x^2 term , so p=0
But that contradicts that 2pqx = 16x
