Question

(x-4)2 (x-9)

I have to put this polynomial in standard form :) Help please

Answer 1

(x-4)²(x-9)

Multiply out the squared factor first (FOIL):

(x²-8x+16)(x-9)

Now multiply by (x-9):

x³ - 8x² + 16x - 9x² + 72x - 144

Now combine like terms and arrange from highest degree (power) to lowest.
