Answer:

$20x^3-14x^2+37x-7$

Explanation: We need to simplify the given expression:

$(4x^2-2x+7)(5x-1)$

Simplification step by step:

$4x^2(5x-1)-2x(5x-1)+7(5x-1)$ $4x^2\times5x-4x^2-2x\times5x+2x+7\times5x-7$ $20x^3-4x^2-10x^2+2x+35x-7=20x^3-14x^2+37x-7$

Therefore this is the simplified expression:
