Simplifying 15b2 + -7bc + -2c2 = 0 Reorder the terms: -7bc + 15b2 + -2c2 = 0 Solving -7bc + 15b2 + -2c2 = 0 Solving for variable 'b'. Factor a trinomial. (3b + -2c)(5b + c) = 0Subproblem 1
Set the factor '(3b + -2c)' equal to zero and attempt to solve: Simplifying 3b + -2c = 0 Solving 3b + -2c = 0 Move all terms containing b to the left, all other terms to the right. Add '2c' to each side of the equation. 3b + -2c + 2c = 0 + 2c Combine like terms: -2c + 2c = 0 3b + 0 = 0 + 2c 3b = 0 + 2c Remove the zero: 3b = 2c Divide each side by '3'. b = 0.6666666667c Simplifying b = 0.6666666667cSubproblem 2
Set the factor '(5b + c)' equal to zero and attempt to solve: Simplifying 5b + c = 0 Solving 5b + c = 0 Move all terms containing b to the left, all other terms to the right. Add '-1c' to each side of the equation. 5b + c + -1c = 0 + -1c Combine like terms: c + -1c = 0 5b + 0 = 0 + -1c 5b = 0 + -1c Remove the zero: 5b = -1c Divide each side by '5'. b = -0.2c Simplifying b = -0.2cSolution
b = {0.6666666667c, -0.2c}
