Synthetic Division & Remainder Theorem For #1-10, use synthetic division to divide the polynomials if possible. If not possible, explain why synthetic division cannot be used, and then use regular division to divide. 1. 4a +4a-12 2a-1 2 . 6a? -5a +10 3 . x - 5x2 +4x -2 3a+2 x - 2 4. x' - 5x2 +4x -2 5 . 2x - 2x+ 1 x+2 6. 2x3 -x2 - 5 2x +4 2x - 5 7 . 2x2 -x+1-4x3 8. 2n* -n -2n+5 n' + 2n+1 = 9. 2x4 -3x2 +7x -8 x+ 2 x2 + x-3 10. x + 4ax?+4ax+ 0 2a+ x
