Simplifying 2c2 + 8 = 8c Reorder the terms: 8 + 2c2 = 8c Solving 8 + 2c2 = 8c Solving for variable 'c'. Reorder the terms: 8 + -8c + 2c2 = 8c + -8c Combine like terms: 8c + -8c = 0 8 + -8c + 2c2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(4 + -4c + c2) = 0 Factor a trinomial. 2((2 + -1c)(2 + -1c)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(2 + -1c)' equal to zero and attempt to solve: Simplifying 2 + -1c = 0 Solving 2 + -1c = 0 Move all terms containing c to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1c = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1c = 0 + -2 -1c = 0 + -2 Combine like terms: 0 + -2 = -2 -1c = -2 Divide each side by '-1'. c = 2 Simplifying c = 2Subproblem 2
