Step-by-step explanation:
Quadratics are second-order polynomials, i.e., equations of variables with exponents summing to at most 2. For example, x^2+3x+2 is a quadratic. Factoring it means finding its roots, so that (x-root1)(x-root2) equals the original quadratic. Being able to factor such a formula is the same as being able to solve the equation x^2+3x+2=0, since the roots are the values of x where the polynomial equals zero.
