10x^2-5x+25 and 3x(x+7)+2(x+7)
-
1. 10x^2 - 5x + 25
Factor out a 5: 5(2x^2 - x + 5)
You can't factor that anymore, so that is you final answer.
2. 3x(x + 7) + 2(x + 7)
Both of these terms have an (x + 7), and you factor that out from both terms:
(x + 7)(3x + 2)
Factor out a 5: 5(2x^2 - x + 5)
You can't factor that anymore, so that is you final answer.
2. 3x(x + 7) + 2(x + 7)
Both of these terms have an (x + 7), and you factor that out from both terms:
(x + 7)(3x + 2)
