find a polynomial of degree 3 with roots 5, 3+4i
x^3-11x^2-6x+5
x^3-22x^2+34x-45
x^3-11x^2+55x-125
x^3-81x^2+50x-3

x=5, x=3%2B4i, or x=3-4i


x-5=0, x-3=4i, or x-3=-4i


x-5=0, %28x-3%29%5E2=%284i%29%5E2, or %28x-3%29%5E2=%28-4i%29%5E2


x-5=0 or %28x-3%29%5E2=-16


x-5=0 or %28x-3%29%5E2%2B16=0


%28x-5%29%28%28x-3%29%5E2%2B16%29=0


%28x-5%29%28x%5E2-6x%2B9%2B16%29=0


%28x-5%29%28x%5E2-6x%2B25%29=0


x%28x%5E2-6x%2B25%29-5%28x%5E2-6x%2B25%29=0


x%5E3-6x%5E2%2B25x-5x%5E2%2B30x-125=0


x%5E3-11x%5E2%2B55x-125=0


So the polynomial of degree 3 with roots 5, 3+4i is x%5E3-11x%5E2%2B55x-125
