Application of the Remainder and Factor Theorem A Directions: Use the remainder theorem and factor theorem to determine if x-risa factor of expressed your answer in factored form (Prove your answer and include your solution) r=3 r=1

1. f(x) = 4x3 - 3x2 - 30x + 9;
2. f(x) = 3x3 - 6x2 - 5x + 8
3.M(x) = **-10x² + 9 r=-1
4.f(x) = x4 -4x3-9x2 + 16x+ 20; r=2
5.f(x) = x3 + x2 -22% – 40; r = 5 ​
