f2 + -0.75o-1r-1 + 2.25o-1r-1x-1 + 0.25o-1r-1x = 0.75o-1r-1 + -0.75o-1r-1 + -2.25o-1r-1x-1 + 2.25o-1r-1x-1 + -0.25o-1r-1x + 0.25o-1r-1x

Combine like terms: 0.75o-1r-1 + -0.75o-1r-1 = 0.00
f2 + -0.75o-1r-1 + 2.25o-1r-1x-1 + 0.25o-1r-1x = 0.00 + -2.25o-1r-1x-1 + 2.25o-1r-1x-1 + -0.25o-1r-1x + 0.25o-1r-1x
f2 + -0.75o-1r-1 + 2.25o-1r-1x-1 + 0.25o-1r-1x = -2.25o-1r-1x-1 + 2.25o-1r-1x-1 + -0.25o-1r-1x + 0.25o-1r-1x

Combine like terms: -2.25o-1r-1x-1 + 2.25o-1r-1x-1 = 0.00
f2 + -0.75o-1r-1 + 2.25o-1r-1x-1 + 0.25o-1r-1x = 0.00 + -0.25o-1r-1x + 0.25o-1r-1x
f2 + -0.75o-1r-1 + 2.25o-1r-1x-1 + 0.25o-1r-1x = -0.25o-1r-1x + 0.25o-1r-1x

Combine like terms: -0.25o-1r-1x + 0.25o-1r-1x = 0.00
f2 + -0.75o-1r-1 + 2.25o-1r-1x-1 + 0.25o-1r-1x = 0.00
