Answer:
32x^3 + 4x^2 + 41x - 35
Step-by-step explanation:
Multiply each of the terms in bracket 1 with those in bracket 2.
4x^2 x 8x = 32x^3
4x^2 x -5 = -20x^2
3x x 8x = 24x^2
3x x -5 = - 15x
7 x 8x = 56x
7 x -5 = -35
Now, put them together and simplify:
32x^3 - 20x^2 + 24x^2 - 15x + 56x - 35
After simplifying:
32x^3 + 4x^2 + 41x - 35
