Before starting this lesson, check your understanding on how to factor ${x^2 + bx + c}$

we talked about in the other lesson first. The coefficient, a, in front of ${x^2}$

can make it a bit more challenging, but we will show you the tricks to make it easy!

- IntroductionOverview of factoring polynomials with a coefficient in front of $x^2$
- 1.Factor the following:a)${9x^2+3x-2}$b)${21x^2-41x+10}$c)${8x^2+x-9}$d)${15x^2-16x-15}$
- 2.Factor with common factoring firsta)${-36x^2-96xy-64y^2}$b)${-3a^2(b+1)^2-2a(b+1)^2+5(b+1)^2}$
- 3.Factor with unusual exponentsa)${-6x^{8a}+17x^{4a}y^{4b}-10y^{8b}}$
