Answer:
x²-x=4
Explanation:
we need to write the equation first so
x ² - 2 x - 8 = 0
+ 8 + 8
x² - 2 x = 8
////////////////// <--- divided
2 2
x² - x = 4
that's the answer
x squared minus 2x minus 8 equals zero, in symbolic form, is
x^2 - 2x - 8 = 0. We don't ask "what is" here, but rather "what are the roots or zeros?"
Please clarify precisely what it is that you wish to calculate here.
