Question

is 4x^2+12x+9 a trinomial square?

Answer 1

if it is it must look like \((a+b)^2\) and since \(3^2=9\) and \((2x)^2=4x^2\) try
\((2x+3)^2\) and see if it works

Answer 2

Its a true or false answer though..

Answer 3

yes i see that
if \((2x+3)^2=4x^2+9x+12\) then it is true.
if not, then it is false
you have to multiply out and see if it works

Answer 4

Thanks :)

Answer 5

btw it is true
