Hi,
Re TY
"the first thing i would do is to get the first and last multiply and then those will have to equal to the middle number"
Yes! 12x + x must equal that middle number 13x
You are definitely getting the hang of it
factoring
(2x + 1)(x + 6) = 0 , x = -1/2 0r x = -6
checking Factoring using FOIL
F First terms
O Outside terms 12x
I Inside terms 1x
L Last terms
