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


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

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

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

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

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

Solving
y = -10 + 3x + x2

Solving for variable 'y'.

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