Question
Solve for all values of xx by factoring.
Given the equation:
Rearranging the equation gives us:
Solution
The equation you provided is x^2 - 87 = -6x.
First, let's rearrange the equation to make it easier to factor. We can do this by adding 6x to both sides of the equation:
x^2 + 6x - 87 = 0
Next, we need to factor the equation. We're looking for two numbers that multiply to -87 and add to 6. Those numbers are 9 and -9.7.
So, we can rewrite the equation as:
(x - 9)(x + 9.7) = 0
Setting each factor equal to zero gives us the solutions to the equation:
x - 9 = 0 => x = 9
x + 9.7 = 0 => x = -9.7
So, the solutions to the equation x^2 - 87 = -6x are x = 9 and x = -9.7.
