To solve the equation −x − 3 = x2 − 2x− 15, you could graph of the following system. y = −x − 3 y = x2 − 2x − 15 use the graph of this system to identify all solutions of −x − 3 = x2 − 2x − 15.

The solution of the equation graphically are (-3,0) and (4,-7).                        

Step-by-step explanation:

Given : Equation

To find : Solve the equation using graph?

Solution :

Let be the equation (1)

be the equation (2)

If we plot the equation (1) and (2) in the graph then the intersection point gives you the solution of the equation.

Equation (1) is shown in blue line.

Equation (2) is shown in red line.

The intersection points of both the equation are (-3,0) and (4,-7).

Therefore, The solution of the equation graphically are (-3,0) and (4,-7).
