I am sure you are trying to type


If that is it, then you should recall the law of exponents which says,


Let us share the exponent for each of them.


We now apply the law,


We now simplify to obtain,



If that is not the expression let me know so I will know how to help you

Answer

5 and -4

Explanation

If the two triangle are congruent then they have the same area.

20 = x² - x

x² - x - 20 = 0

x² - x + (1/2)² = 20 + (1/2)²

(x - 1/2)² = 20.25

x - 1/2 = √20.25

x - 1/2 = 4.5                             or    x - 1/2 = - 4.5

x = 4 1/2 + 1/2                                      x = -4 1/2 + 1/2

   = 5                                                      = -4

The values of x are 5 and -4.
