Multiply. (x^2+ 3x + 2)•(2x^2+ 3x - 1)

see explanation

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

x²(2x² + 3x - 1) + 3x(2x² + 3x - 1) + 2(2x² + 3x - 1)

Distribute all 3 parenthesis

= 2 + 3x³ - x² + 6x³ + 9x² - 3x + 4x² + 6x - 2

Collect like terms

= 2 +9x³ + 12x² + 3x - 2

the least common denominator is 40

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
