Question

fSolve each equation. Leave the answer as an improper fraction.

3x2 + 2 = 11 - x2

Answer 1

3x^2+x^2=11-2


Solve further? @dfrazier2

Answer 2

3x^2 + 2 = 11 - x^2 --- add x^2 to both sides
3x^2 + x^2 + 2 = 11 --- subtract 2 from each side
3x^2 + x^2 = 11 - 2 --- combine like terms
4x^2 = 9 --- divide both sides by 4
x^2 = 9/4 -- take sq rt of each side
x = sq rt 9/4
x = sq rt 2 1/4 or 2.25
x = 1.5

Answer 3

oops...leave as improper fraction....
x = sq rt 9/4 ??

Answer 4

Thankz
