Help me with this problem

Answer 1

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

Step-by-step 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*5x-4x^2-2x*5x+2x+7*5x-7`
`20x^3-4x^2-10x^2+2x+35x-7=20x^3-14x^2+37x-7`

Therefore this is the simplified expression:
