Answer 4

ight

Answer 5

ight man

Answer 6

wait you're doing the quadratic formula?

Answer 7

yea

Answer 8

Oh man than thats easy x'd alright

Answer 9

Alright so basically you know the Quadratic formula: \(ax^2 + bx+c=0\)

Find a, b, c.

Answer 10

As I already have shown the formula ax..
"a"=2;
"bx":b=-4
and "c":y-5

Now put them in the quadratic formulaa

Answer 11

\[x=\frac{ \sqrt{(-4)^2-4*2(y-5)} }{ 2*2 }\]

Answer 12

y = -2 (x + 2 - 4)^2 + y - 5

Answer 13

Now solve in the square root first start from \(-4*2(y-5)\) than as also \(-4)^2\) square root it and add

Answer 14

jfc i forgot the \(4\pm\) in front of the quadratic formula

Answer 15

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