Question

is x=-2 a solution of the equation x^-2x+8=0?

Answer 1

Plug in -2 in place of x

Answer 2

You should write it as x2 - 2x + 8 = 0. I think that's what you mean?

To see if x=-2 is a solution, replace x with -2 in the equation and see what happens...

Answer 3

hmn. I mean you should write as x^2 - 2x + 8 = 0 ...
