Which polynomial represents (6 x 2 −x−9)(4x−7)?

The answer to your question is 24x³ - 46x²- 28x + 63

Step-by-step explanation:

Data

               (6x² - x - 9)(4x - 7)

Process

1.- Multiply 4x by the three terms of the first polynomial

           (6x² - x - 9)(4x) = 24x³ - 4x² - 36x

2.- Multiply -7 by the three terms of the first polynomial

           (6x² - x - 9)(-7) = -42x² + 7x + 63

3.- Add both result

           24x³ - 4x² - 36x -42x² + 7x + 63 = 24x³ - 46x²- 28x + 63

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
