Solution for (c-3)(c-3)=9 equation:


Simplifying
(c + -3)(c + -3) = 9

Reorder the terms:
(-3 + c)(c + -3) = 9

Reorder the terms:
(-3 + c)(-3 + c) = 9

Multiply (-3 + c) * (-3 + c)
(-3(-3 + c) + c(-3 + c)) = 9
((-3 * -3 + c * -3) + c(-3 + c)) = 9
((9 + -3c) + c(-3 + c)) = 9
(9 + -3c + (-3 * c + c * c)) = 9
(9 + -3c + (-3c + c2)) = 9

Combine like terms: -3c + -3c = -6c
(9 + -6c + c2) = 9

Add '-9' to each side of the equation.
9 + -6c + -9 + c2 = 9 + -9

Reorder the terms:
9 + -9 + -6c + c2 = 9 + -9

Combine like terms: 9 + -9 = 0
0 + -6c + c2 = 9 + -9
-6c + c2 = 9 + -9

Combine like terms: 9 + -9 = 0
-6c + c2 = 0

Solving
-6c + c2 = 0
