Question 7
Factor x^2-7x-18

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?

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 4x^2 - 19x- 5

How can you find the mean absolute deviation (mad) for this set of data?
