7(x - 2y)
7x(3x3 - 2x2 + 5x + 1)
6x2 + 7x - 5 = (3x + 5)(2x - 1)
49x2 - 84x + 36 = (7x - 6)(7x - 6) or (7x - 6)2
(3x+1)(x+2)
7(x - 2y)
Look for the GCF. 7, 14 and 21 all have 7 as a common factor. Divide that out. 7x divided by 7 = x 21 divided by 7 = 3 14y divided by 7 = 2y 7x + 21 + 14y = 7(x + 3 + 2y)
(y + 7)(y + 7)
(3b + 7x)(3b + 7x) or (3b + 7x)2
(y-12)(y-2)
(3y - 2)(y - 4)
7x + 7 = 7(x + 1)

You would factor 2x2 + 7x + 6 into (2x + 3) (x+2)
x2 + 7x + 6 = (x + 6) (x + 1)
7x(3x3 - 2x2 + 5x + 1)
49x2+28x+4 = (7x+2)(7x+2) when factored
