Best ResponseYou've already chosen the best response.2Dont use FOIL, I can't believe FOIL is even used these days. Just "break up" the middle term

Best ResponseYou've already chosen the best response.2what 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

Best ResponseYou've already chosen the best response.0\[5x^2+5x7x7=0, 5x(x+1)7(x+1)=0, (5x7)(x+1)=0\] 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
