(6z+5)(6z-5)=

Solution for (6z+5)(6z-5)= equation:

Simplifying
(6z + 5)(6z + -5) = 0

Reorder the terms:
(5 + 6z)(6z + -5) = 0

Reorder the terms:
(5 + 6z)(-5 + 6z) = 0

Multiply (5 + 6z) * (-5 + 6z)
(5(-5 + 6z) + 6z * (-5 + 6z)) = 0
((-5 * 5 + 6z * 5) + 6z * (-5 + 6z)) = 0
((-25 + 30z) + 6z * (-5 + 6z)) = 0
(-25 + 30z + (-5 * 6z + 6z * 6z)) = 0
(-25 + 30z + (-30z + 36z2)) = 0

Combine like terms: 30z + -30z = 0
(-25 + 0 + 36z2) = 0
