Learn how to solve classify algebraic expressions problems step by step online. Find the break even points of the expression xx+81=0. When multiplying two powers that have the same base (x), you can add the exponents. We need to isolate the dependent variable x, we can do that by simultaneously subtracting 81 from both sides of the equation. Canceling terms on both sides. Removing the variable's exponent.

Final answer to the problem

$x=9i,\:x=-9i$
