Use a generic rectangle to multiply the factors together then distribute the negative and solve.
Set the equation equal to 0. Then use a generic rectangle to factor and solve for x using the Zero Product Property.
Solve for the absolute value then make two equations to remove the absolute value.
x − 3 = 4 or x − 3 = −4
x = 7 or x = −1
Test numbers to determine which region is the solution.
