WebFactor the equation by grouping. Negative Terms. In some situations, a is negative, as in −ax 2 + bx + c. To make the factoring of the trinomial simpler, we factor out -1 from ax 2 as the first step and factor the rest of the expression. Let us look at an example. Example: Factorize -4x 2 - 8x - 3. WebAPTeamOfficial. 1. Multiply your a-value by c. (You get y^2-33y-784) 2. Attempt to factor as usual (This is quite tricky for expressions like yours with huge numbers, but it is easier than keeping the a coeffcient in.) If you find the two values, you should get (y+16) (y-49).

Factoring by Grouping - Basic Mathematics
WebWe’ll do a few examples on solving quadratic equations by factorization. Example 1: 4x −12x2 = 0 4 x − 12 x 2 = 0. Given any quadratic equation, first check for the common factors. In this example, check for the common factors among 4x 4 x and 12x2 12 x 2. We can observe that 4x 4 x is a common factor.
