What is the measure of ac? 5 units 13 units 26 units 39 units

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. 3, 4+2i, 1+(sqrt)7 the answer is supposed to be: f(x)=x(^5)-13x(^4)+60x(^3)-82x(^2)-144x+360 what am i doing wrong?

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
