## How do you know if a function has real solutions?

But since there is only one max/min point, this means that the graph intersects with the x-axis at only this one point – meaning it only has one root. When a graph only intersects the x-axis at one point, and therefore only has one root, this indicates that it has one real solution.

## How do you find the solution set of a quadratic equation?

As our equation is in the form 𝑎𝑥 squared plus 𝑏𝑥 plus 𝑐 is equal to zero, we can solve it using the quadratic formula. This states that 𝑥 is equal to negative 𝑏 plus or minus the square root of 𝑏 squared minus four 𝑎𝑐 all divided by two 𝑎. The positive and negative signs give us two solutions.

## How do you find the roots of a quadratic function?

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) 0, and solve the equation, ax2 + bx + c 0.

## What is the easiest way to find the roots of a quadratic equation?

The roots of any quadratic equation is given by: x [-b +/- sqrt(-b^2 – 4ac)]/2a. Write down the quadratic in the form of ax^2 + bx + c 0. If the equation is in the form y ax^2 + bx +c, simply replace the y with 0. This is done because the roots of the equation are the values where the y axis is equal to 0.
