Factor [math]5y^2 – 45[/math], and then verify your results.
[list=1] [*]Determine any common factors of the given binomial, if common factors exist. [*]Determine if the binomial [math]y^2 – 9[/math] meets the conditions of the difference of two squares. [*]Use the pattern [math]x^2 – y^2 = (x + y)(x – y)[/math] to factor the binomial. [*]Multiply the factors to verify they result in the original binomial.
