Dont use FOIL, I can't believe FOIL is even used these days.
Just "break up" the middle term
how did u get 5x^2 + 5x - 7x -7 ?
what you do is break up the middle number into 2 numbers, the combinations can be infinite but among them, you choose 2 numbers which are multiples of each number at the corners
hope that helped
\[5x^2+5x-7x-7=0, 5x(x+1)-7(x+1)=0, (5x-7)(x+1)=0\] they way your gona split middle term should give the product of two end terms , like 7*5= 35 , so were gona split middle term in a way so that we can get 35, thats y we wrote -2x=-7x+5x
take 5*7= will be 35
group it 5x^2+5x common is
-7x+7 common is 7 but pull out -1
