(7a-1) (x^2+2x-5)

7ax2+14ax-x2-35a-2x+5

Step-by-step explanation:

(7a+-1) (x2+2x+-5)

= (7a) (x2) + (7a) (2x) + (7a) (-5) + (-1) (x2) + (-1) (2x) + (-1) (-5)

=7ax2+14ax-35a-x2-2x+5

=7ax2+14ax-x2-35a-2x+5

Step-by-step explanation:

(7a - 1) (x² + 2x - 5) = 7a * ((x² + 2x - 5) + (-1) * (x² + 2x - 5)

= 7a*x² + 7a*2x + 7 * (-5) + (-1) * x² + (-1) * 2x + - 5*-1

= 7ax² + 14ax - 35 - x² - 2x + 5

= 7ax² - x² + 14ax - 2x - 30
