y=2(x+1)(x+2)

Solution for y=2(x+1)(x+2) equation:

Simplifying
y = 2(x + 1)(x + 2)

Reorder the terms:
y = 2(1 + x)(x + 2)

Reorder the terms:
y = 2(1 + x)(2 + x)

Multiply (1 + x) * (2 + x)
y = 2(1(2 + x) + x(2 + x))
y = 2((2 * 1 + x * 1) + x(2 + x))
y = 2((2 + 1x) + x(2 + x))
y = 2(2 + 1x + (2 * x + x * x))
y = 2(2 + 1x + (2x + x2))

Combine like terms: 1x + 2x = 3x
y = 2(2 + 3x + x2)
y = (2 * 2 + 3x * 2 + x2 * 2)
y = (4 + 6x + 2x2)

Solving
y = 4 + 6x + 2x2

Solving for variable 'y'.

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

Simplifying
