I don't think you will be able to sovle this by factoring. If you are not familiar with the quadratic formula, you probably won't be able to follow my explanation, but, we can find the roots of a quadratic equation (that is, the x values where the equation is 0) using the quadratic formula:

For now, let's focus on

The equation tells us a = 32, b = 7 and c = -81, substituting these values into the formula, we get:

. This is not a perfect square, so factoring won't work, however, continuing with the quadratic formula will.

This gives us a factorization of 32(x - 1.48537)(x + 1.7041)
