The polynomial 3x2 - 27<br />can be factored in 2 steps:<br />3x2 – 27 = 3(x2 – 9)<br /> = 3(x + 3)(x – 3)<br />When a polynomial is factored into irreducible polynomials that have no common factor, then it is factored completely.<br />

Steps in factoring completely:<br />1. Look for the GCF<br />2. Look for special cases.<br />difference of two squares<br />perfect square trinomial<br />3. If a trinomial is not a perfect square, look for two different binomial factors.<br />8t4 – 32t3 + 40t <br /> = 8t(t3 - 4t + 5)<br />4x2 – 9y2 = (2x)2 – (3y)2<br />x2 + 8x + 16 = x2 + 8x + 42<br />= (x + 4)2<br />6x2 + 11x – 10 <br /> = (2x + 5)(3x – 2)<br />
