In triangle​ ABC, the size of angle B is times the size of angle​ A, and the size of angle C is less than times the size of angle A. Find the size of the angles

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 is the answer to this question? i'm a bit stumped. also how do i do it? 5(x - 4) = 2(x + 5)

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined
