Two rectangular, adjacent rooms share a wall. One foot by one foot tiles cover the floor of each room.

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?

Math it's appreciated. (picture provided)
