6 + 2z + 3z + 2z2 = 3z(z + 2) + (-1z * -1z)

Combine like terms: 2z + 3z = 5z
6 + 5z + 2z2 = 3z(z + 2) + (-1z * -1z)

Reorder the terms:
6 + 5z + 2z2 = 3z(2 + z) + (-1z * -1z)
6 + 5z + 2z2 = (2 * 3z + z * 3z) + (-1z * -1z)
6 + 5z + 2z2 = (6z + 3z2) + (-1z * -1z)

Reorder the terms for easier multiplication:
6 + 5z + 2z2 = 6z + 3z2 + (-1 * -1z * z)

Multiply -1 * -1
6 + 5z + 2z2 = 6z + 3z2 + (1z * z)

Multiply z * z
6 + 5z + 2z2 = 6z + 3z2 + (1z2)

Combine like terms: 3z2 + (1z2) = 4z2
6 + 5z + 2z2 = 6z + 4z2

Solving
6 + 5z + 2z2 = 6z + 4z2

Solving for variable 'z'.

Reorder the terms:
6 + 5z + -6z + 2z2 + -4z2 = 6z + 4z2 + -6z + -4z2

Combine like terms: 5z + -6z = -1z
6 + -1z + 2z2 + -4z2 = 6z + 4z2 + -6z + -4z2

Combine like terms: 2z2 + -4z2 = -2z2
6 + -1z + -2z2 = 6z + 4z2 + -6z + -4z2

Reorder the terms:
6 + -1z + -2z2 = 6z + -6z + 4z2 + -4z2

Combine like terms: 6z + -6z = 0
6 + -1z + -2z2 = 0 + 4z2 + -4z2
6 + -1z + -2z2 = 4z2 + -4z2

Combine like terms: 4z2 + -4z2 = 0
6 + -1z + -2z2 = 0
