# Solve the quadratic formula when a=5, b=12, and c=3 and also solve it with a=3, b=-5, and c=-9

I'm trying to solve the quadratic formula with these numbers, but my answers always ended up not being whole numbers. Can you solve it for me and tell me what you get?

# What is f(x)?

I dont understand how to solve quadratic functions. I'm supposed to solve f(x)-x^2+2x-3 by completing the square  but whenever I try to search how to do these kind of problems, I never see...

# how to use the quadratic formula

the problem 7x^2+123x-4

# How do you factor an equation like ax^2+bx+c if the a is negative and there is no c?

I know how to graph these kinds of equations with parabolas but cannot figure out how to find the factored, vertex, and standard forms of these equations.
