Answer:
x is all reall numbers
(∞,-∞)
Step-by-step explanation:
Multiply both sides of the equation by [tex]50 X 7x^{x}[/tex] so it will be
[tex]7x^{x+2} +7x^{x} =(50X7x^{x} )X1[/tex]
then when we solve for x it will be 0=0 / Since 0
=
0
, the equation will always be true for any value of x is All real numbers
