Please help me with this problem so I can help my son. I have attached the image of the problem from his homework paper that he was working on in class please help.

1) Let's factor this quadratic, by rewriting that coefficient "b" as -4x+2x, this is possible since we have the coefficient a greater than 1 and by doing that we can write coefficients that share divisors with the leading coefficient 2 and the coefficient c = 12
[tex]\begin{gathered} 2x^{2}-2x-12=0 \\ 2(x^2-x-6)=0 \\ 2(x^2+2x-3x-6)=0 \\ 2x(x^{}+2)-3(x+2) \\ (2x-3)(x+2) \end{gathered}[/tex]Note that when we find a repetition (x+2) on both factors then we can rewrite as a product.
