Solution for y=ln(x+3)*ln(x-1) equation:


Simplifying
y = ln(x + 3) * ln(x + -1)

Reorder the terms:
y = ln(3 + x) * ln(x + -1)

Reorder the terms:
y = ln(3 + x) * ln(-1 + x)

Reorder the terms for easier multiplication:
y = ln * ln(3 + x)(-1 + x)

Multiply ln * ln
y = l2n2(3 + x)(-1 + x)

Multiply (3 + x) * (-1 + x)
y = l2n2(3(-1 + x) + x(-1 + x))
y = l2n2((-1 * 3 + x * 3) + x(-1 + x))
y = l2n2((-3 + 3x) + x(-1 + x))
y = l2n2(-3 + 3x + (-1 * x + x * x))
y = l2n2(-3 + 3x + (-1x + x2))

Combine like terms: 3x + -1x = 2x
y = l2n2(-3 + 2x + x2)
y = (-3 * l2n2 + 2x * l2n2 + x2 * l2n2)
y = (-3l2n2 + 2l2n2x + l2n2x2)

Solving
y = -3l2n2 + 2l2n2x + l2n2x2

Solving for variable 'y'.

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

Simplifying
y = -3l2n2 + 2l2n2x + l2n2x2
