Rewrite in simplest terms: -7(2u-6v)-7v-3(10v+u)

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

Write the expression in simplified radical form. show all steps and work including any foil method work. (hint: use the conjugate. no decimal answers.) (9-2√3)/(12+√3)

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
