i was supposed to do something in every class for this whole week but i literally did nothing- so i spent 15 minutes using inspect element to edit it all and make it look like i did it.. so while i was waiting for my mom i was playing a game even tho she said not to. so when she walked in i quickly exited out but i accidentally clicked it twice and exited out of the inspect elemented things what should i do pls help fast

sorry mate, I got no idea.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

not sure but it may be b, as i said i'm not sure.
