$-12x+x^2=-36$

Short answer

The solution to the equation $-12x+x^2=-36$ is x=6.

Step-by-step solution

Step 1. Given Information.

Given to solve the equation $-12x+x^2=-36$ by graphing. And if the exact roots cannot be found, the consecutive integers between which the roots are located are to be determined.

Step 2. Explanation.

A quadratic equation has a real solution where the graph of the related function crosses or touches the x-axis.

Graphing the given equation using graphing calculator:

From the given graph, the function crosses the x axis at 6.

Hence the solution to the equation $-12x+x^2=-36$is x=6.

Step 3. Conclusion.

Therefore, the solution to the equation $-12x+x^2=-36$ is x=6
