Please help me. I can't figure this out. I've been doing math for 5 hours and that's not an exaggeration.

Well you have to do PEMDAS

So we have an exponent so that will turn into a positive X

X+4x=10

So now we combine our X's together to get 5X=10

Now we divide both sides by X which gives us 2

Answer

Center: (1,-12)

Radius: 5

Work

$x^{2}$ + $y^{2}$ -2x+24y+120=0 (Subtract 120 on both sides and rearrange)

$x^{2}$ -2x+ $y^{2}$ +24y=-120 (Then divide 2 by 2 and square it. Do the same for 24.)

$x^{2}$ -2x+1+ $y^{2}$ +24y+144=-120+1+144 (You have to add the same numbers on both sides)

$(x-1)^{2} +(y+12)^2=25$ (Simplify)

So you would put (1,-12); r=5
