Question

solve using quadratic formula.
x^2+(x+10)^2=50 solve using quadratic formula.
x^2+(x+10)^2=50 @Mathematics

Answer 1

\[x ^{2}+x ^{2}+20x+100-50=0\] \[2x ^{2}+20x+50=0\]
a=2 b=20 c=50
\[\frac{-b \pm \sqrt{b ^{2}-4ac}}{2a}\]
\[\frac{-20 \pm \sqrt{20 ^{2}-4*2*50}}{2*2}\]

Answer 2

\[\frac{-20 \pm \sqrt{400-400}}{4}\]\[\frac{-20 }{4}\]=-5

Answer 3

x=-5
