7. Factor the result using the
factor() function.
8. Multiply both sides of the
equation by 4añ.
9. Take the square root of both
sides of the equation with the
constraint that a>0 and b>0 and
x>0.
10.Solve for x by subtracting b
from both sides and then
dividing by 2a.
Note: This is only one of the
two general quadratic
solutions due to the
constraint in step 9.
