Set the single term factor on the left side of the equation equal to 0 0 . x=0 x = 0.
Set each of the factors of the left side of the equation equal to 0 0 . ...
Since −10 - 10 does not contain the variable to solve for, move it to the right side of the equation by adding 10 10 to both sides. ...
Solve the equations for x x .
A^2 - b^2 = (a - b)( a +b);
