Solve -x² - 4x + 12 = 0 for x.

-x² - 4x + 12 = 0

-1(x² + 4x - 12) = 0 {factored -1 out}

x² + 4x - 12 = 0 {divided each side by -1}

(x + 6)(x - 2) = 0 {factored into two binomials}

x + 6 = 0 or x - 2 = 0 {set each factor equal to zero}

-1(x² + 4x - 12) = 0 {factored -1 out}

x² + 4x - 12 = 0 {divided each side by -1}

(x + 6)(x - 2) = 0 {factored into two binomials}

x + 6 = 0 or x - 2 = 0 {set each factor equal to zero}

**x = -6 or x = 2**{solved each equation}**Ask the House**
