Rewrite the function by completing the square.
h(x)=x^2+3x-18

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation h*(x)-(x^2+3*x-18)=0

Step-by-step explanation:

Equation at the end of step 1 :

hx - x2 - 3x + 18 = 0

Step 2 :

Solving a Single Variable Equation :

2.1 Solve hx-x2-3x+18 = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.
