2ay2 + 5ay - 3a = a(2y2 + 5y - 3) = a(2y - 1)(y + 3)
3a+ax+3b+bx = 3(a+b)+(a+b)x = (a+b)(3+x)
3ab + 3ac + 2b2 + 2bc = 3a(b + c) + 2b(b + c) = (3a + 2b)(b + c)
15a - 25b + 20 = 5 (3a - 5b + 4)
0
2ay2 + 5ay - 3a = a(2y2 + 5y - 3) = a(2y - 1)(y + 3)
3a(2a + 1)
You would factor 3a + 9b as: 3(a+3b)
9a^2 + 42at + 49t^2 = (3a + 7t)(3a + 7t)
(3a - 4)(3a - 4)
(x + 3)(a + b)
(2a+1)(a+1)
3a+ax+3b+bx = 3(a+b)+(a+b)x = (a+b)(3+x)
a(a^2 - 9a + 3)
The GCF is a.
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
a(b+3)+b(b+3)
