Hey there!

$\bold{x^2=5-x}$ Firstly, add the "x" value on each of your sides $\bold{x^2+x=5-x+x}$ Simplify that part of your equationWe get: $\bold{x^2+x=5}$ Now we have to subtract by the number 5 on each of your sides $\bold{x^2+x-5=5-5}$ Simplify that part of the equation as wellWe get: $\bold{x^2+x-5=0}$ USE THE QUADRATIC FORMULA TO MAKE IT EASIER TO SOLVE $\boxed{\boxed{\bold{x=\frac{-1+\sqrt{21}}{2};x=\frac{=1-\sqrt{21} }{2}}}}$ (A)
