Multiply (x − 4)(x2 + 6x − 5). x3 + 2x2 − 29x + 20
x3 − 5x2 − 14x + 20
x3 + 6x2 − 13x + 20
x3 + 10x2 − 19x + 20

x3 + 2x2 − 29x + 20

Step-by-step explanation:

x(x2+6x−5)−4(x2+6x−5)

x3+6x2−5x−4(x2+6x−5)

x3+6x2−5x−4x2−24x+20

x3+2x2−5x−24x+20

x3 + 2x2 − 29x + 20

a 10 percent increase

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
