Solution for in(x+3)+in(x-1)=0 equation:


Simplifying
in(x + 3) + in(x + -1) = 0

Reorder the terms:
in(3 + x) + in(x + -1) = 0
(3 * in + x * in) + in(x + -1) = 0
(3in + inx) + in(x + -1) = 0

Reorder the terms:
3in + inx + in(-1 + x) = 0
3in + inx + (-1 * in + x * in) = 0
3in + inx + (-1in + inx) = 0

Reorder the terms:
3in + -1in + inx + inx = 0

Combine like terms: 3in + -1in = 2in
2in + inx + inx = 0

Combine like terms: inx + inx = 2inx
2in + 2inx = 0

Solving
2in + 2inx = 0

Solving for variable 'i'.

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

Factor out the Greatest Common Factor (GCF), '2in'.
2in(1 + x) = 0

Ignore the factor 2.

Subproblem 1

Set the factor 'in' equal to zero and attempt to solve: Simplifying in = 0 Solving in = 0 Move all terms containing i to the left, all other terms to the right. Simplifying in = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 0 Move all terms containing i to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Add '-1x' to each side of the equation. x + -1x = -1 + -1x Combine like terms: x + -1x = 0 0 = -1 + -1x Simplifying 0 = -1 + -1x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
