(a-8)(a+2)=

Solution for (a-8)(a+2)= equation:

Simplifying
(a + -8)(a + 2) = 0

Reorder the terms:
(-8 + a)(a + 2) = 0

Reorder the terms:
(-8 + a)(2 + a) = 0

Multiply (-8 + a) * (2 + a)
(-8(2 + a) + a(2 + a)) = 0
((2 * -8 + a * -8) + a(2 + a)) = 0
((-16 + -8a) + a(2 + a)) = 0
(-16 + -8a + (2 * a + a * a)) = 0
(-16 + -8a + (2a + a2)) = 0

Combine like terms: -8a + 2a = -6a
(-16 + -6a + a2) = 0

Solving
-16 + -6a + a2 = 0

Solving for variable 'a'.
