2x%5E3-26%5E2%2B80x
= 2x%28x%5E2-13x%2B40%29

= 2x%28x%5E2-5x-8x%2B40%29

= 2x%2A%28x%28x-5%29-8%28x-5%29%29

= 2x%2A%28x-5%29%2A%28x-8%29 Answer. First of all factorise the expression by the common factor i.e. 2x. Then factorise x^2-13x+40 into (x-5)(x-8). As these factors cannot be further factorised, 2x*(x-5)(x-8) is the Answer. I hope this is clear to you.
