Find the distance between (1,2) and (5,5)

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?

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
