s^2+2s+sf+2f=0

Solution for s^2+2s+sf+2f=0 equation:

Simplifying
s2 + 2s + sf + 2f = 0

Reorder the terms:
2f + fs + 2s + s2 = 0

Solving
2f + fs + 2s + s2 = 0

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Add '-2s' to each side of the equation.
2f + fs + 2s + -2s + s2 = 0 + -2s

Combine like terms: 2s + -2s = 0
2f + fs + 0 + s2 = 0 + -2s
2f + fs + s2 = 0 + -2s
Remove the zero:
2f + fs + s2 = -2s

Add '-1s2' to each side of the equation.
2f + fs + s2 + -1s2 = -2s + -1s2

Combine like terms: s2 + -1s2 = 0
2f + fs + 0 = -2s + -1s2
2f + fs = -2s + -1s2

Reorder the terms:
2f + fs + 2s + s2 = -2s + 2s + -1s2 + s2

Combine like terms: -2s + 2s = 0
2f + fs + 2s + s2 = 0 + -1s2 + s2
2f + fs + 2s + s2 = -1s2 + s2

Combine like terms: -1s2 + s2 = 0
2f + fs + 2s + s2 = 0
