How do you do factoring in algebra?

If the equation is in the form a2-b2, factor it to (a+b)(a-b). Equations with two variables factor differently than basic quadratics. For any equation a2-b2 where a and b do not equal 0, the equation factors to (a+b)(a-b). For example, the equation 9×2 – 4y2 = (3x + 2y)(3x – 2y).
