Solution for y=(b+4)(b-2) equation:


Simplifying
y = (b + 4)(b + -2)

Reorder the terms:
y = (4 + b)(b + -2)

Reorder the terms:
y = (4 + b)(-2 + b)

Multiply (4 + b) * (-2 + b)
y = (4(-2 + b) + b(-2 + b))
y = ((-2 * 4 + b * 4) + b(-2 + b))
y = ((-8 + 4b) + b(-2 + b))
y = (-8 + 4b + (-2 * b + b * b))
y = (-8 + 4b + (-2b + b2))

Combine like terms: 4b + -2b = 2b
y = (-8 + 2b + b2)

Solving
y = -8 + 2b + b2

Solving for variable 'y'.
