Answer
$4x^{2} -12x +9$
Work Step by Step
$(2x-3)^{2}$
1. Square the first term inside the bracket. $(2x)^{2} = 4x^{2}$
2. Multiply the first term and second term inside the bracket together. Then multiply this answer by 2. So $(2x)(-3)(2) = -12x$
3. Square the last term inside the bracket. $(-3)^{2} = 9$
4. Add all your answers from steps 1-4 to get $4x^{2} -12x +9$.
