Solve the polynomial equation. In order to obtain the first root, use synthetic division to test the possible rational roots.
5.2x^313x^2+22x8=0
My answer:{1/2,2,4}
6.x^38x^2x+8=0
My answer: {1,1,8}
Find the rational zero of the polynomial function and use it to find all the zeros of the function.
3. f(x)=x^3+3x^24x12
My answer: {3,2,2}
4. f(x)3x^314x^2+13x+6
My answer: {1/3,2,3}

you are correct in all cases
