If you make one of the parentheses equal to zero then the whole left side is equal to zero (because zero multiplied by anything is zero). So you'd set the first set of parentheses like so: (x-2)=0. Then to isolate "x", you would add 2 to both sides to get x=2.

WebOct 6, 2024 · Key Concepts. A parabola is the set of all points (x,y) in a plane that are the same distance from a fixed line, called the directrix, and a fixed point (the focus) not on the directrix. The standard form of a parabola with vertex (0,0) and the x -axis as its axis of symmetry can be used to graph the parabola. WebNov 9, 2024 · We can see from the graph that the parabola intersects the x-axis (the line y = 0) at x = 2 and x= 6. At this point, we know that the solutions of the equation are x = 2 and x = 6. However, we can find the quadratic equation as well. First, the quadratic factored form looks like this: y = a (x – r) (x – s)

WebIf you need to graph a sideways parabola in your graphing calculator (to check your work, for instance), you'll need to solve the equation for its two halves, and then graph the two halves as two separate functions.
