Solution for (8-v)(8+v)= equation:


Simplifying
(8 + -1v)(8 + v) = 0

Multiply (8 + -1v) * (8 + v)
(8(8 + v) + -1v * (8 + v)) = 0
((8 * 8 + v * 8) + -1v * (8 + v)) = 0
((64 + 8v) + -1v * (8 + v)) = 0
(64 + 8v + (8 * -1v + v * -1v)) = 0
(64 + 8v + (-8v + -1v2)) = 0

Combine like terms: 8v + -8v = 0
(64 + 0 + -1v2) = 0
(64 + -1v2) = 0
