QuestionAssignment: Show complete solution 1 Perform the following multiplications and simplify your results: (a) $(8 x-4)\left(4 x^{2}-3 x+2\right)$ (b) $(2 x+3)\left(5 x^{3}+3 x-4\right)$

Studdy Solution
Combine like terms.
$10x^4 + 15x^3 + 6x^2 + (-8x + 9x) - 12 = 10x^4 + 15x^3 + 6x^2 + x - 12$
$(2x + 3)(5x^3 + 3x - 4) = 10x^4 + 15x^3 + 6x^2 + x - 12$
Solution to (a): $(8x - 4)(4x^2 - 3x + 2) = 32x^3 - 40x^2 + 28x - 8$
Solution to (b): $(2x + 3)(5x^3 + 3x - 4) = 10x^4 + 15x^3 + 6x^2 + x - 12$
