Answer 1

Answer:

3   x^2 +12x-9

Step-by-step explanation:

5x^2 - (2x-3)^2

We need to FOIL the second term

(2x-3)^2  = (2x-3) (2x-3)  = 4x^2 -6x-6x+9 = 4x^2 -12x+9

Replacing it in to the original equation

5x^2 - (4x^2 -12x+9)

Distribute the minus sign

5x^2 - 4x^2 +12x-9

Combine like terms

x^2 +12x-9

Answer 2

Answer:

Your answer is Number 3

Step-by-step explanation:

$(2x-3)^{2} =\\(2x-3)(2x-3)=\\4x^{2} -6x-6x+9=\\4x^{2}-12x+9\\5x^{2}-(4x^{2}-12x+9)\\ -12x+9\\5x^{2}-(4x^{2}-12x+9)\\ 5x^{2} -4x^{2} +12x-9=\\x^{2}+12x-9$\\
