x2-2x = 15
x2-2x-15 = 0
(x-5)(x+3) = 0
Therefore: x = 5 or x = -3
the graph of a quadratic function is a parabola. hope this helps xP
A parabola is a U-shaped graph.
A parabola.
You should always use the vertex and at least two points to graph each quadratic equation. A good choice for two points are the intercepts of the quadratic equation.
inverse linear or quadratic

the graph for a quadratic equation ct5r
Draw the graph of the equation. the solution is/are the points where the line cuts the x(horisontal) axis .
When you graph the quadratic equation, you have three possibilities... 1. The graph touches x-axis once. Then that quadratic equation only has one solution and you find it by finding the x-intercept. 2. The graph touches x-axis twice. Then that quadratic equation has two solutions and you also find it by finding the x-intercept 3. The graph doesn't touch the x-axis at all. Then that quadratic equation has no solutions. If you really want to find the solutions, you'll have to go to imaginary solutions, where the solutions include negative square roots.
Yes it is possible. The solutions for a quadratic equation are the points where the function's graph touch the x-axis. There could be 2 places to that even if the graph looks different.
The graph of a quadratic equation has the shape of a parabola.
It is the graph of a quadratic equation of the formy = ax^2 + bx + c

It will have two equal roots.
You write the equation in such a way that you have zero on the right side. Then you graph the expression on the left side of the equal sign, and check where it touches the x-axis. Note that this method works for most common equations.
But there will be a solution if the discriminant is equal to zero: Real and different roots if b2-4ac > 0 Real and equal roots if b2-4ac = 0 But no real roots if b2-4ac < 0 in other words the graph wont make contact with or intercept the x axis.
