There are a number of methods we can use to factor polynomials: factoring out the greatest common factor (GCF), factoring by grouping, factoring the difference of two squares, and factoring the sum or difference of two cubes. The first step in factoring is always to factor out the if any...
Factor the polynomial {eq}3x^2+23x+30 {/eq} by grouping. Notice that this polynomial is a quadratic trinomial. In this case, the middle term can be broken up into a sum. To find the numbers of this sum, we need to multiply the coefficient of the leading term by the last term,...

Solve using factoring by grouping: 12x^2 + 11x + 2 = 0 How do you solve for b in 10b^2 = 27b - 18 by factoring? How do you solve for x in x^2 + x - 30 = 0 by factoring? How do you solve for x in x^2 + 3x - 18 = 0 by factoring?
Factoring by grouping:This is a method for factoring polynomials when they have four or more terms. The terms are grouped in pairs, and the greatest common factor (GCF) is factored out from each pair. Factoring trinomials: This is the process of breaking down a trinomial into the product of...
We use the shortcut method instead of factoring by grouping.The general form of trinomials with a leading coefficient of a is ax2+bx+cax2+bx+c. Sometimes the factor of a can be factored as you saw above; this happens when a can be factored out of all three terms. The remaining ...
