Can you please answer this equation in completing the square formula... X-5√x+4=0
Please can you give the answer..


Sagot :

[tex]x-5 \sqrt{x} +4=0[/tex]
We can do quadratic equation but the result would be the square root of x
[tex] \frac{5±\sqrt{25-16} }{2} = \sqrt{x} [/tex]
the possible values for the square root of x is either 4 or 1, we square the numbers 
so x is either 16 or 1
