Question 50544: "Factor the following polynomials without a calculator. No decimal answers. Exact answers only in completely reduced form. Show all work for credit. Circle final answer." Jeez, how much more specific can they get?!
How do you do this?
You can put this solution on YOUR website! key form: (a + b)(a - b) = a^2 - b^2
ex.) (2x - 1)(2x + 1) = 4x^2 - 1
ex.) (x - 3)(x + 3) = x^2 - 9
(100x^2 - 3) = (10x - sqrt(3))(10x + sqrt(3))
Works the other way.
