Simplifying 0 = 3(5x2 + -4x + -16) Reorder the terms: 0 = 3(-16 + -4x + 5x2) 0 = (-16 * 3 + -4x * 3 + 5x2 * 3) 0 = (-48 + -12x + 15x2) Solving 0 = -48 + -12x + 15x2 Solving for variable 'x'. Combine like terms: 0 + 48 = 48 48 + 12x + -15x2 = -48 + -12x + 15x2 + 48 + 12x + -15x2 Reorder the terms: 48 + 12x + -15x2 = -48 + 48 + -12x + 12x + 15x2 + -15x2 Combine like terms: -48 + 48 = 0 48 + 12x + -15x2 = 0 + -12x + 12x + 15x2 + -15x2 48 + 12x + -15x2 = -12x + 12x + 15x2 + -15x2 Combine like terms: -12x + 12x = 0 48 + 12x + -15x2 = 0 + 15x2 + -15x2 48 + 12x + -15x2 = 15x2 + -15x2 Combine like terms: 15x2 + -15x2 = 0 48 + 12x + -15x2 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(16 + 4x + -5x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(16 + 4x + -5x2)' equal to zero and attempt to solve: Simplifying 16 + 4x + -5x2 = 0 Solving 16 + 4x + -5x2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. -3.2 + -0.8x + x2 = 0 Move the constant term to the right: Add '3.2' to each side of the equation. -3.2 + -0.8x + 3.2 + x2 = 0 + 3.2 Reorder the terms: -3.2 + 3.2 + -0.8x + x2 = 0 + 3.2 Combine like terms: -3.2 + 3.2 = 0.0 0.0 + -0.8x + x2 = 0 + 3.2 -0.8x + x2 = 0 + 3.2 Combine like terms: 0 + 3.2 = 3.2 -0.8x + x2 = 3.2 The x term is -0.8x. Take half its coefficient (-0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. -0.8x + 0.16 + x2 = 3.2 + 0.16 Reorder the terms: 0.16 + -0.8x + x2 = 3.2 + 0.16 Combine like terms: 3.2 + 0.16 = 3.36 0.16 + -0.8x + x2 = 3.36 Factor a perfect square on the left side: (x + -0.4)(x + -0.4) = 3.36 Calculate the square root of the right side: 1.833030278 Break this problem into two subproblems by setting (x + -0.4) equal to 1.833030278 and -1.833030278.Subproblem 1
x + -0.4 = 1.833030278 Simplifying x + -0.4 = 1.833030278 Reorder the terms: -0.4 + x = 1.833030278 Solving -0.4 + x = 1.833030278 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.4' to each side of the equation. -0.4 + 0.4 + x = 1.833030278 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + x = 1.833030278 + 0.4 x = 1.833030278 + 0.4 Combine like terms: 1.833030278 + 0.4 = 2.233030278 x = 2.233030278 Simplifying x = 2.233030278Subproblem 2
x + -0.4 = -1.833030278 Simplifying x + -0.4 = -1.833030278 Reorder the terms: -0.4 + x = -1.833030278 Solving -0.4 + x = -1.833030278 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.4' to each side of the equation. -0.4 + 0.4 + x = -1.833030278 + 0.4 Combine like terms: -0.4 + 0.4 = 0.0 0.0 + x = -1.833030278 + 0.4 x = -1.833030278 + 0.4 Combine like terms: -1.833030278 + 0.4 = -1.433030278 x = -1.433030278 Simplifying x = -1.433030278Solution
