Question

15/2x^2 = 15/5-x^2

Answer 1

are you solving for x

Answer 2

yes

Answer 3

well then, add x^2 to both sides and what do you get?

Answer 4

x^4

Answer 5

not hardly,
(15/2)*x^2 + x^2 = (15/2+1)*x^2
you just add the numbers in front of the x^2

Answer 6

so (15/2 + 1) = 15/2+2/2 = 17/2
so now the equation is 17/2*x^2 = 15/5

Answer 7

give me a sec checking

Answer 8

ok take your time

Answer 9

sorry trying to help a friend out with this she didnt have an account here

Answer 10

so is there a step after that?

Answer 11

yes
so from there you can say
17/2*x^2 = 3 (which was 15/5)
so divide both sides by (17/2) and get
x^2 = 3/(17/2) which is the same as
x^2 = 3*(2/17) which is
x^2 = 6/17
then just take the square root of both sides to find x

Answer 12

thank you she got it

Answer 13

awesome. :)
