Question

please help..ill give a medal (:

Answer 1

\[2x=\sqrt{20+2x}\]

Answer 2

Start by squaring both sides. This eliminates the radical:
\[4x^2 = 20 + 2x\] Subtract the 20 and the 2x from both sides to get a quadratic equation:
\[4x^2 -2x -20=0\] From here you could try factoring or plugging in to the quadratic formula. If you need more help with solving this let me know.

Answer 3

like first step you can factorizing out 2 and divide both sides by 2 and so will get

2x^2 -x -10 = 0

Answer 4

ohhhhh ok thank you!
