As I already have shown the formula ax.. "a"=2; "bx":b=-4 and "c":y-5 Now put them in the quadratic formulaa
alones:
\[x=\frac{ \sqrt{(-4)^2-4*2(y-5)} }{ 2*2 }\]
mikewwe13:
y = -2 (x + 2 - 4)^2 + y - 5
alones:
Now solve in the square root first start from \(-4*2(y-5)\) than as also \(-4)^2\) square root it and add
alones:
jfc i forgot the \(4\pm\) in front of the quadratic formula

Anyways as you solve this out your answer should be: \[x=4\pm2\frac{ \sqrt{2(7-y)} }{ 4 }\]
