(Math)In the Equation y=axx+bx+c, How can i combine axx+c with bx and how do i put it on a graph?

Please this is one of the few things i need to know

To put it on a graph just let x equal a series of numbers say 1,2,3,4,5 and then substitute them into the equation and solve for y. Then plot them on a graph.
Reply:y = ax^2 + bx + c





You can't really combine them into one term, if that's what you're asking. All you have to do is use the fact that it's a parabola, and you can obtain





1) the x-intercept(s), if any


2) the y-intercept


3) the vertex





Those would be some sketching guides right there, as soon as you learn how to get them.
