Question

(2x^2-3x+1)(x^2-4x-3)

Answer 1

B

Explanation:

Given

(2x² - 3x + 1)(x² - 4x - 3)

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

2x²(x² - 4x - 3) - 3x(x² - 4x - 3) + 1(x² - 4x - 3) ← distribute parenthesis

= 2
`x^(4)` - 8x³ - 6x² - 3x³ + 12x² + 9x + x² - 4x - 3 ← collect like terms

= 2
`x^(4)` - 11x³ + 7x² + 5x - 3 → B
