Solution for (c+3)(c-7)= equation:


Simplifying
(c + 3)(c + -7) = 0

Reorder the terms:
(3 + c)(c + -7) = 0

Reorder the terms:
(3 + c)(-7 + c) = 0

Multiply (3 + c) * (-7 + c)
(3(-7 + c) + c(-7 + c)) = 0
((-7 * 3 + c * 3) + c(-7 + c)) = 0
((-21 + 3c) + c(-7 + c)) = 0
(-21 + 3c + (-7 * c + c * c)) = 0
(-21 + 3c + (-7c + c2)) = 0

Combine like terms: 3c + -7c = -4c
(-21 + -4c + c2) = 0

Solving
-21 + -4c + c2 = 0

Solving for variable 'c'.
