How To Find X Intercepts Of A Parabola?

How do you find the x intercept of a quadratic equation?

To find the x-intercepts of a quadratic equation, let y = 0.

Write down the new equation ax squared + bx + c = 0 and the quadratic formula that gives the solution as x = -b plus or minus the square root of (b squared – 4ac), all divided by 2a.

Which of the following can be the number of x intercepts for a parabola?

A parabola can have 2 x-intercepts, 1 x-intercept or zero real x intercepts. If the parabola only has 1 x-intercept (see middle of picture below), then the parabola is said to be tangent to the x-axis.

How do you find the x intercept algebraically?

To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x. You can also use the graph of the line to find the x intercept. Just look on the graph for the point where the line crosses the x-axis, which is the horizontal axis. That point is the x intercept.
