Question

I’m struggling with this problem, can you try and explain it to me?

Answer 1

we have the expression

`(x+3)(2x-4)`

Applying distributive property

`\begin{gathered} (x+3)(2x-4) \\ \begin{equation*} x(2x)-x(4)+3(2x)-3(4) \end{equation*} \\ 2x^2-4x+6x-12 \\ 2x^2+2x-12 \end{gathered}`

therefore

a=2

b=2

c=-12
