hope it helps

Answer 2

`32x^3+4x^2+41x-35`

Explanation:

Given expression is,

`(4x^2+3x+7)(8x-5)`

Using the distributive property,

`(4x^2+3x+7)(8x)-(4x^2+3x+7)(5)`

Again by distributive property,

`4x^2(8x)+3x(8x)+7(8x)-4x^2(5)-3x(5)-7(5)`

`32x^3+24x^2+56x-20x^2-15x-35`

Combine like terms,

`32x^3+4x^2+41x-35`
