Question 1163693
.
<pre>

1x − 4 + 1x + 3 = 1x2 − x − 12


First, simplify


2x - 1 = x^2 - x - 12

x^2 - 3x - 11 = 0


Now, by applying the Rational root theorem, you can conclude that no one integer number is the solution,

and even more, no one rational number is the solution.


This conclusion works without solving equation.
