Hey!
To solve x in this equation we must first add five to both sides to get
on its own.
<em>Original Equation :</em>
<em>New Equation {Added 5 to Both Sides} :</em>
Now we must square both sides of the equation.
<em>Old Equation :</em>
<em>New Equation {Changed by Squaring Both Sides} :</em>
And now we must solve the new equation.
Step 1 - Switch sides
Step 2 - Subtract x from both sides
Step 3 - Simplify
Now we need to solve the rest of the equation using the quadratic formula.
