Question

What is the factored form of 2x^2 + x – 3?

Answer 1

(2x+3)(x-1)

Answer 2

how did you get that?

Answer 3

Well, factoring means, splitting and re-writing the equation in the form of (ax+b)(cx+d) where a, b, c and d can be any numbers.

That requires you to either take a guess, like did and found the right values, or use the quadratic formula.

In this case, if you use my factors and expand them out, you get the original equation:
(2x+3)(x-1) = 2x^2 -2x + 3x - 3 = 2x^2 + x - 3.
