Solution for y=(2x+1)(x-5)(x+3) equation:


Simplifying
y = (2x + 1)(x + -5)(x + 3)

Reorder the terms:
y = (1 + 2x)(x + -5)(x + 3)

Reorder the terms:
y = (1 + 2x)(-5 + x)(x + 3)

Reorder the terms:
y = (1 + 2x)(-5 + x)(3 + x)

Multiply (1 + 2x) * (-5 + x)
y = (1(-5 + x) + 2x * (-5 + x))(3 + x)
y = ((-5 * 1 + x * 1) + 2x * (-5 + x))(3 + x)
y = ((-5 + 1x) + 2x * (-5 + x))(3 + x)
y = (-5 + 1x + (-5 * 2x + x * 2x))(3 + x)
y = (-5 + 1x + (-10x + 2x2))(3 + x)

Combine like terms: 1x + -10x = -9x
y = (-5 + -9x + 2x2)(3 + x)

Multiply (-5 + -9x + 2x2) * (3 + x)
y = (-5(3 + x) + -9x * (3 + x) + 2x2 * (3 + x))
y = ((3 * -5 + x * -5) + -9x * (3 + x) + 2x2 * (3 + x))
y = ((-15 + -5x) + -9x * (3 + x) + 2x2 * (3 + x))
y = (-15 + -5x + (3 * -9x + x * -9x) + 2x2 * (3 + x))
y = (-15 + -5x + (-27x + -9x2) + 2x2 * (3 + x))
y = (-15 + -5x + -27x + -9x2 + (3 * 2x2 + x * 2x2))
y = (-15 + -5x + -27x + -9x2 + (6x2 + 2x3))

Combine like terms: -5x + -27x = -32x
y = (-15 + -32x + -9x2 + 6x2 + 2x3)

Combine like terms: -9x2 + 6x2 = -3x2
y = (-15 + -32x + -3x2 + 2x3)

Solving
y = -15 + -32x + -3x2 + 2x3

Solving for variable 'y'.

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

Simplifying
y = -15 + -32x + -3x2 + 2x3
