Answer: 21x^2 + 44x + 15
Step-by-step explanation:
<em>first, i used the distributive property.</em>
5x x (4 + 7x - 1) + 5 (4 + 7x - 1) - 2x x (4 + 7x - 1)
<em>then, i removed the parentheses. </em>
20x + 35x^2 - 5x + 20 + 35x - 5 - 8x - 14x^2 + 2x
<em>then, i collected the like terms.</em>
44x + 21x^2 + 15
<em>finally, i reordered the terms.</em>
21x^2 + 44x + 15
