why can t x 2 9 be factored The first term is a perfect square since 4 x 2 2 x 2 and the last term is a perfect square since 9 3 2 Also the middle term is twice the product of the numbers that are squared since 12 x 2 2 x 3 We can use the perfect square trinomial pattern to factor the quadratic
Popular Problems Algebra Factor x 2 9 x2 9 x 2 9 Rewrite 9 9 as 32 3 2 x2 32 x 2 3 2 Since both terms are perfect squares factor using the difference of squares formula a2 b2 a b a b a 2 b 2 a b a b where a x a x and b 3 b 3 x 3 x 3 x 3 x 3 x 2 16 left x 4 right left x 4 right This is completely factored since neither of the two factors on the right can be further factored Likewise x 4 16 left x 2 4 right left x 2 4 right is not completely factored because the second factor can be further factored
