Can you help me please!

Given f(x) = 2x^2- 5x+1, determine the function value f(2). do not f(x) = in your answer

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?

If you are trying to move an attached term across the equal sign (=), what operation would you use to move it?
