(c-6)(c-4)=

Solution for (c-6)(c-4)= equation:

Simplifying
(c + -6)(c + -4) = 0

Reorder the terms:
(-6 + c)(c + -4) = 0

Reorder the terms:
(-6 + c)(-4 + c) = 0

Multiply (-6 + c) * (-4 + c)
(-6(-4 + c) + c(-4 + c)) = 0
((-4 * -6 + c * -6) + c(-4 + c)) = 0
((24 + -6c) + c(-4 + c)) = 0
(24 + -6c + (-4 * c + c * c)) = 0
(24 + -6c + (-4c + c2)) = 0

Combine like terms: -6c + -4c = -10c
(24 + -10c + c2) = 0

Solving
24 + -10c + c2 = 0

Solving for variable 'c'.

0 + -1c = 0 + -6
-1c = 0 + -6

Combine like terms: 0 + -6 = -6
-1c = -6

Divide each side by '-1'.
c = 6

Simplifying
c = 6
Solution
c = {4, 6}
