Simplifying 4x2 + 28x + -150 = 0 Reorder the terms: -150 + 28x + 4x2 = 0 Solving -150 + 28x + 4x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-75 + 14x + 2x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-75 + 14x + 2x2)' equal to zero and attempt to solve: Simplifying -75 + 14x + 2x2 = 0 Solving -75 + 14x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -37.5 + 7x + x2 = 0 Move the constant term to the right: Add '37.5' to each side of the equation. -37.5 + 7x + 37.5 + x2 = 0 + 37.5 Reorder the terms: -37.5 + 37.5 + 7x + x2 = 0 + 37.5 Combine like terms: -37.5 + 37.5 = 0.0 0.0 + 7x + x2 = 0 + 37.5 7x + x2 = 0 + 37.5 Combine like terms: 0 + 37.5 = 37.5 7x + x2 = 37.5 The x term is 7x. Take half its coefficient (3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. 7x + 12.25 + x2 = 37.5 + 12.25 Reorder the terms: 12.25 + 7x + x2 = 37.5 + 12.25 Combine like terms: 37.5 + 12.25 = 49.75 12.25 + 7x + x2 = 49.75 Factor a perfect square on the left side: (x + 3.5)(x + 3.5) = 49.75 Calculate the square root of the right side: 7.05336799 Break this problem into two subproblems by setting (x + 3.5) equal to 7.05336799 and -7.05336799.Subproblem 1
x + 3.5 = 7.05336799 Simplifying x + 3.5 = 7.05336799 Reorder the terms: 3.5 + x = 7.05336799 Solving 3.5 + x = 7.05336799 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = 7.05336799 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = 7.05336799 + -3.5 x = 7.05336799 + -3.5 Combine like terms: 7.05336799 + -3.5 = 3.55336799 x = 3.55336799 Simplifying x = 3.55336799Subproblem 2
x + 3.5 = -7.05336799 Simplifying x + 3.5 = -7.05336799 Reorder the terms: 3.5 + x = -7.05336799 Solving 3.5 + x = -7.05336799 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3.5' to each side of the equation. 3.5 + -3.5 + x = -7.05336799 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + x = -7.05336799 + -3.5 x = -7.05336799 + -3.5 Combine like terms: -7.05336799 + -3.5 = -10.55336799 x = -10.55336799 Simplifying x = -10.55336799Solution
