Question

Find the product of (x-2) and (3x^2-4x-5)

Answer 1

3x³ - 10x² + 3x + 10

Explanation:

multiply 'x' by each term in the second expression:

(x-2)(3x²-4x-5) = 3x³ -4x² - 5x

now multiply '-2' by each term in the second expression:

-6x² + 8x + 10

combine 'like' terms: -4x² + (-6x²) to get -10x²

combine 'like' terms: 8x - 5x = 3x

answer: 3x³ - 10x² + 3x + 10
