Re: factoring problems :(

Read up: Algebra House Factoring Examples

x^2 - 2x -63
= (x - 9)(x + 7) {factored into two binomials}

x^2 +15x+16
= does not factor

x^2 + 14xy +45y^2
= (x + 9y)(x + 5y) {factored into two binomials}

5x^2 - 5x -30
= 5(x² - x - 6) {factored 5 out}
= 5(x - 3)(x + 2) {factored into two binomials}

105 -36x + 3x^2
= 3x² - 36x + 105 {switched around}
= 3(x² - 12x + 35) {factored 3 out}
= 3(x - 7)(x - 5) {factored into two binomials}

2x^2 +14x-12
= 2(x² + 7x - 6) {factored 2 out}
 
x^3 - 5x^2 -6x
= x(x² - 5x - 6) {factored x out}
= x(x - 6)(x + 1) {factored into two binomials}
