Given the following trinomial expression:
[tex]4x^2+12x+9[/tex]
The given expression is a complete square.
the factor of the given trinomial will be as follows:
[tex]4x^2+12x+9=(2x+3)(2x+3)[/tex]
A student gives the answer (2x-3)(2x-3).
So, by comparing the student's answer to our answer, we can note the student is wrong in the sign
So, the answer will be:
C. The minus signs should be plus signs
