(b-c)(a+b)-ac
If you're solving for b, then you use the quadratic formula to factor out b. In this case, b= -1/4 or -18/12
3ab + 3ac + 2b2 + 2bc = 3a(b + c) + 2b(b + c) = (3a + 2b)(b + c)
2(5c + 2d)(5c + 2d)
(a + 2 - b) (a + 2 + b)
(a+b)(a squared-ab+b squared)
(a+b)(3b+1)
(b + 8)(b + 4)
(b + 4)(b + 4)
(a + x^2)(b + y^2)
(b + 2c)(b - c)

(b + 8)(b - 1)

Remember to factor out the GCF of the coefficients if there is one. A perfect square binomial will always follow the pattern a squared plus or minus 2ab plus b squared. If it's plus 2ab, that factors to (a + b)(a + b) If it's minus 2ab, that factors to (a - b)(a - b)
(b-c)(a+b)-ac
