Question

x^2+100X-1000 find the real solution if any. using quadratic formula.

Answer 1

easier to complete the square which is the same only without the huge computation

Answer 2

true, but i have to solve the equation in the form givin i assume. but not sure. could be a trick question lol.

Answer 3

x_1,_2=(-100 +/- sqrt(10000 +4000))/2

Answer 4

\[x^2+100x-1000=0\]
\[x^2+100x=1000\]
\[(x-50)^2=1000+50^2=3500\]
\[x+50=\pm\sqrt{3500}=\pm10\sqrt{35}\]
\[x=-50\pm10\sqrt{35}\]
