Question 71871
1) Factor:
{{{9t^2+36t}}} What are the factors of each term?
{{{9t^2 = (3)(3)(t)(t)}}} and {{{36t = (2)(2)(3)(3)(t)}}}
{{{(3)(3)(t)(t) + (2)(2)(3)(3)(t)}}} Find the common factors and take them outside of the parentheses.
{{{(3)(3)(t)*(t+2*2)}}} Now simplify this.
{{{9t(t+4)}}}
2) Factor:
{{{14zx-18xz^2}}} Factor each term.
{{{(2)(7)(z)(x) - (2)(3)(3)(x)(z)(z)}}} Take out the common factors from each term.
{{{(2)(x)(z)(7-9z)}}} Simplify.
{{{2xz(7-9z)}}}
