I want to eat and bought a hamburger a bag of chips and a drink all the chips cost $1.25 gave the cashier $20 and received $14.39 in how what did the drink cost

Using the quadratic formula find the zeros of the given polynomial -5x^2+3x-11

F(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 h(x) = x + 5 arrowright h(x) = x + 3 arrowright h(x) = x + 4 arrowright h(x) = x − 1 arrowright

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)
