Question

Multiply 3x^2-2x and 2x^2+3x-1

Answer 1

6
`x^(4)` + 5x³ - 9x² + 2x

Explanation:

Given

(3x² - 2x)(2x² + 3x - 1)

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

= 3x²(2x² + 3x - 1) - 2x(2x² + 3x - 1) ← distribute both parenthesis

= 6
`x^(4)` + 9x³ - 3x² - 4x³ - 6x² + 2x ← collect like terms

= 6
`x^(4)` + 5x³ - 9x² + 2x
