Answer:
A) 9x^2-12x+4
Step-by-step explanation:
to find out whether an equation is a perfect square when we take the square root of "a" and the square root of "c" and double their sum. The result should be the middle term, -12
so
square root of 9; 3
square root of 4: 2
2((3*-2))=-12
now we can take the square root of 9x^2(which is 3x) and the square root of 4(-2) and put it in a expression like this
(3x-2)^2
hope this helps!
