What is (5x+6) to the 2nd power using the foil method?
-------
(5x+6)(5x+6)
---
F: 5x * 5x = 25x^2
O: 5x * 6 = 30x
I: 5x * 6 = 30x
L: 6 * 6 = 36
-----------------
Combine to get the answer:
25x^2 + 60x + 36

(5x+6)(5x+6)
Foil
First so that would be 5x*5X=25x^2
Outer that is 5x*6= 30x
Inner this is the 5x*6 again which you know is 30X
and
Last is 6*6 =36
if you combine you will ge
25x^2 + 30x + 30x +36
now you must simplify by combining like terms.
25X^2 + 60X + 36
now an easier way to do an equation like this is by using the formula
(ax+b)^2 = (ax)^2 + 2ab + b^2
