8(m+n)
2x+2 The commonality is 2, so you write 2(x+1) and it is factored.
w2+18w+77 = (w+7)(w+11) when factored
4(2b+5)
(x + 5)2
8(m+n)
9x2+2x-7 = (9x-7)(x+1) when factored
2x+2 The commonality is 2, so you write 2(x+1) and it is factored.
10ab + 15b = 5b (2a + 3)
2(a+b) is 2a plus 2b in factored form.
It is (x+4)(x+5) when factored
w2+18w+77 = (w+7)(w+11) when factored
18 + 8x + x = = 18 + 9x = 9(2 + x) which is the factored form of the expression.
2x + 3 can be factored as follows: 2(x + 1.5)
6x2+5x+1 = (3x+1)(2x+1) when factored
It can't be factored because its discriminant is less than zero
2x(3x + 5)
