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


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

Reorder the terms:
5z(5 + 5z) + 6z(5z + -6) = 0
(5 * 5z + 5z * 5z) + 6z(5z + -6) = 0
(25z + 25z2) + 6z(5z + -6) = 0

Reorder the terms:
25z + 25z2 + 6z(-6 + 5z) = 0
25z + 25z2 + (-6 * 6z + 5z * 6z) = 0
25z + 25z2 + (-36z + 30z2) = 0

Reorder the terms:
25z + -36z + 25z2 + 30z2 = 0

Combine like terms: 25z + -36z = -11z
-11z + 25z2 + 30z2 = 0
