y = x^3 -10x^2 +17x-8

Explanation:

Step 1: Multiply and expand the function and combine like terms

y= (x-8)(x-1)^2

y = (x-8)(x-1)(x-1)
y= (x^2-8x-x+8)(x-1)
y= (x^2 -9x +8)(x-1)

*Step 28: Multiply and expand and combine like terms like this

y= (x^2 -9x +8)(x-1)

y = (x^3 -x^2 -9x^2 +9x +8x-8)
y = x^3 -10x^2 +17x-8
