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

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

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

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

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

Multiply (1 + x) * (-1 + x)
-1(1(-1 + x) + x(-1 + x))(3 + x) = 0
-1((-1 * 1 + x * 1) + x(-1 + x))(3 + x) = 0
-1((-1 + 1x) + x(-1 + x))(3 + x) = 0
-1(-1 + 1x + (-1 * x + x * x))(3 + x) = 0
-1(-1 + 1x + (-1x + x2))(3 + x) = 0

Combine like terms: 1x + -1x = 0
-1(-1 + 0 + x2)(3 + x) = 0
-1(-1 + x2)(3 + x) = 0

Multiply (-1 + x2) * (3 + x)
-1(-1(3 + x) + x2(3 + x)) = 0
-1((3 * -1 + x * -1) + x2(3 + x)) = 0
-1((-3 + -1x) + x2(3 + x)) = 0
-1(-3 + -1x + (3 * x2 + x * x2)) = 0
-1(-3 + -1x + (3x2 + x3)) = 0
-1(-3 + -1x + 3x2 + x3) = 0
(-3 * -1 + -1x * -1 + 3x2 * -1 + x3 * -1) = 0
(3 + 1x + -3x2 + -1x3) = 0

Solving
3 + 1x + -3x2 + -1x3 = 0

Solving for variable 'x'.
