Answer:
8x^3 - 26x^2 + 17x - 5.
Explanation:
(2x - 5)(4x^2 - 3x + 1)
= (2x * 4x^2) + (-5 * 4x^2) + (2x * -3x) + (-5 * -3x) + (2x * 1) + (-5 * 1)
= 8x^3 + (-20x^2) + (-6x^2) + 15x + 2x - 5
= 8x^3 - 26x^2 + 17x - 5.
Hope this helps!
33x-6x(square)-45
(2x-5)(9-3x)
= 2x(9-3x) + -5(9-3x)
= 18x-6x(square) - 45+15x
= 33x-6x(square)-45
