= (x - 4)(4x² - 6x + 7)
= 4x³ - 6x² + 7x - 16x² + 24x - 28
= 4x³ - 22x² + 31x - 28
Answer: 4x³ - 22x² + 31x - 28
= 4x³ - 6x² + 7x - 16x² + 24x - 28
= 4x³ - 22x² + 31x - 28
Answer: 4x³ - 22x² + 31x - 28

sounds like someone doesn't want to do their homework or they didn't pay attention in class

(x - 4)(4x^2 - 6x + 7)
= x*4x^2 - 4*4x^2 - x*6x + 4*6x + x*7 - 4*7
= 4x^3 - 16x^2 - 6x^2 + 24x + 7x - 28
= 4x^3 - 22x^2 + 31x - 28
= x*4x^2 - 4*4x^2 - x*6x + 4*6x + x*7 - 4*7
= 4x^3 - 16x^2 - 6x^2 + 24x + 7x - 28
= 4x^3 - 22x^2 + 31x - 28

(x-4) (4x^ - 6x +7)
= 4x^2(x-4) -6x(x-4) + 7(x-4)
= 4x^2(x) + 4x^(-4) -6x(x) -6x(-4) + 7(x) + 7(-4)
= 4x^3 - 16x^ -6x^ +24x +7x -28
= 4x^3 -22x^ +31x - 28
= 4x^2(x-4) -6x(x-4) + 7(x-4)
= 4x^2(x) + 4x^(-4) -6x(x) -6x(-4) + 7(x) + 7(-4)
= 4x^3 - 16x^ -6x^ +24x +7x -28
= 4x^3 -22x^ +31x - 28
