Distribute the x to both 6 and -1 and get: 3x² + 6 x -x -2. Then factor by grouping: 3x(x+2) + (-1) (x+2) = (3x-1) (x +2). This is the final answer. Step 5 Check the answer by multiplying the binomials (3x-1) (x +2) and compare to the quadratic equation ...
3x^3 + 8x^2 - 9x + 2 is an example. You can't use grouping to factor out a GCF in a way that would produce a common factor. In order to explain how this works, you need to know that when solving an equation by factoring, you need to set the factored out thing equal to 0 ...
