Question
Solve for all values of xx by factoring.x, squared, minus, 81, equals, 0x 2 −81=0
Solution
Sure, here are the steps to solve the equation:
-
Write down the equation: x^2 - 81 = 0
-
Notice that this is a difference of squares, which can be factored into (x - 9)(x + 9).
-
Set each factor equal to zero and solve for x:
x - 9 = 0 => x = 9
x + 9 = 0 => x = -9
So, the solutions to the equation x^2 - 81 = 0 are x = 9 and x = -9.
