Find the zero function by factoring (try to show work) h(x)=-x^2-6x-9

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

Find the zeros of each function. f(x) = 6x^2 - 7x - 20
