y=2(x+3)(x+5)

Solution for y=2(x+3)(x+5) equation:

Simplifying
y = 2(x + 3)(x + 5)

Reorder the terms:
y = 2(3 + x)(x + 5)

Reorder the terms:
y = 2(3 + x)(5 + x)

Multiply (3 + x) * (5 + x)
y = 2(3(5 + x) + x(5 + x))
y = 2((5 * 3 + x * 3) + x(5 + x))
y = 2((15 + 3x) + x(5 + x))
y = 2(15 + 3x + (5 * x + x * x))
y = 2(15 + 3x + (5x + x2))

Combine like terms: 3x + 5x = 8x
y = 2(15 + 8x + x2)
y = (15 * 2 + 8x * 2 + x2 * 2)
y = (30 + 16x + 2x2)

Solving
y = 30 + 16x + 2x2

Solving for variable 'y'.
