# How To Find The Intersection With The Coordinate Axis

The
intersection of the X axis is obtained by finding the random variable value x
in the quadratic function if the value of variable y is zero, then the
intersection point (x

The abc formula can be proven by the following steps,

Suppose there is an equation squared with y = 0,

_{1}, 0) and (x_{2}, 0) will be obtained, where x_{1}and x_{2}are the roots of the equation square. But keep in mind that the roots of equations depend on discriminant.- If D < 0, then the function does not have the roots of quadratic equations so the graph sketch of the quadratic function does not cut the X-axis.
- If D> 0, then the function has the roots of the quadratic function equation but we have difficulty solving the solution because the number that is factored is a decimal number. Where the values of these roots can be obtained by the
**abc formula**, After we get the values x_{1}and x_{2}, the intersection points of the quadratic function are (x_{1}, 0) and (x_{2}, 0)

The abc formula can be proven by the following steps,

Suppose there is an equation squared with y = 0,

ax

^{2}+ bx + c = 0**First**, the two segments are divided by a.

**S**

**econd**, the two segments are reduced by c / a.

**Third**, complete the perfect quadratic equation by adding the square of the half times the coefficient of x, so that later you can factor the section next to it.

**Fifth**, the square root of both segments.

**Sixth**, subtract the two sections by b / 2a.

This is the abc formula
that we often use in solving quadratic equations.

- The intersection with the
Y axis is obtained by finding the y value in the quadratic function if the
value of the variable x is zero, so that the point (0, y
_{1}) is obtained.
