Answer:
The value comes out to be
![x=\frac{1}{2}+\frac{\sqrt{17}}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B2%7D%2B%5Cfrac%7B%5Csqrt%7B17%7D%7D%7B2%7D)
Step-by-step explanation:
The quadratic equation is an equation containing a single variable of degree
. Its general form is
.
The discriminant is the part of the quadratic formula underneath the square root symbol: b²- 4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.
The equation we are given is :![x+4=x^{2} \\x^{2} -x-4=0\\](https://tex.z-dn.net/?f=x%2B4%3Dx%5E%7B2%7D%20%5C%5Cx%5E%7B2%7D%20-x-4%3D0%5C%5C)
We know the formula as :
±
×![\frac{1}{2a}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2a%7D)
±
×![\frac{1}{2(1)}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%281%29%7D)
±![\frac{\sqrt{17} }{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B17%7D%20%7D%7B2%7D%20%7D)
Since
≥![0](https://tex.z-dn.net/?f=0)
Other negative option is neglected
![x=\frac{1}{2}+\frac{\sqrt{17}}{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B2%7D%2B%5Cfrac%7B%5Csqrt%7B17%7D%7D%7B2%7D)
