Megam factored the expression -12^2+52x-35 as (-2x+5)(6x-7) but when Jacob applied the foil principle and multiplied out (-2x+5)(6x-7) he got -12x^2+44x^2+44x-35; thus megans solution does not appear to check. Why is that? Please help Megan to understand. Explain your reasoning and correctly factor the orginalexpression if possible. If the expression is prime state so.

-12x^2+52x-35

-12x^2+52x-35 = (-2x+7)(6x-5)

(-2x+7)(6x-5) = -2x*6x -2x(-5) + 7*6x + 7(-5)=

- 12x^2 + 10x + 42x - 35 =

- 12x^2 + 52x - 35
