Answer:
-1
Step-by-step explanation:
You can write it as...
![x^{2} -5=4x](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-5%3D4x)
Carry the 4x
![x^{2} -4x-5=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%20-4x-5%3D0)
Then use the quadratic formula to solve, since you want to find the negative solution, you don't need to find the positive solution, so we will have
![(4-\sqrt{16+20}) /2=\frac{4-6}{2}=\frac{-2}{2} =-1](https://tex.z-dn.net/?f=%284-%5Csqrt%7B16%2B20%7D%29%20%2F2%3D%5Cfrac%7B4-6%7D%7B2%7D%3D%5Cfrac%7B-2%7D%7B2%7D%20%3D-1)
Therefore our answer is -1
