Solution for 20=(2x-z)(z+2) equation: 


Simplifying
20 = (2x + -1z)(z + 2)

Reorder the terms:
20 = (2x + -1z)(2 + z)

Multiply (2x + -1z) * (2 + z)
20 = (2x * (2 + z) + -1z * (2 + z))
20 = ((2 * 2x + z * 2x) + -1z * (2 + z))
20 = ((4x + 2xz) + -1z * (2 + z))
20 = (4x + 2xz + (2 * -1z + z * -1z))
20 = (4x + 2xz + (-2z + -1z2))
20 = (4x + 2xz + -2z + -1z2)

Solving
20 = 4x + 2xz + -2z + -1z2
