Question 308412
{{{8x^2-18}}} factor out a 2
{{{2(4x^2-9)}}}inside "()" is a perfect square so factoring is easy
{{{highlight(2(2x-3)(2x+3))}}}if u cant come to this solution use the quadratic formula, but this factoring of a square is much faster. the square looks like this:{{{2^2x^2-3^2}}} since b=0 in the abc for the quadratic formula then there will be one factor with a "+" and one with a "-"
