Question

Please help me in this question
Give the answers as well as explanation

Answer 1

a) = 0, 4^2 - 4(4) = 0, 0 x g(x) = 0
b) also 0, a and b are basically the same thing
c) I think it’s also 0 because you take 4^2 - 4(4) = 0, 0x0 = 0
d) (4+9)(4+9)
= (13)(13)
=169

not sure if I’m completely right but I think it’s right
