Simplifying 30x2 + -87x + -54 = 0 Reorder the terms: -54 + -87x + 30x2 = 0 Solving -54 + -87x + 30x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '3'. 3(-18 + -29x + 10x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-18 + -29x + 10x2)' equal to zero and attempt to solve: Simplifying -18 + -29x + 10x2 = 0 Solving -18 + -29x + 10x2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -1.8 + -2.9x + x2 = 0.0 Move the constant term to the right: Add '1.8' to each side of the equation. -1.8 + -2.9x + 1.8 + x2 = 0.0 + 1.8 Reorder the terms: -1.8 + 1.8 + -2.9x + x2 = 0.0 + 1.8 Combine like terms: -1.8 + 1.8 = 0.0 0.0 + -2.9x + x2 = 0.0 + 1.8 -2.9x + x2 = 0.0 + 1.8 Combine like terms: 0.0 + 1.8 = 1.8 -2.9x + x2 = 1.8 The x term is -2.9x. Take half its coefficient (-1.45). Square it (2.1025) and add it to both sides. Add '2.1025' to each side of the equation. -2.9x + 2.1025 + x2 = 1.8 + 2.1025 Reorder the terms: 2.1025 + -2.9x + x2 = 1.8 + 2.1025 Combine like terms: 1.8 + 2.1025 = 3.9025 2.1025 + -2.9x + x2 = 3.9025 Factor a perfect square on the left side: (x + -1.45)(x + -1.45) = 3.9025 Calculate the square root of the right side: 1.975474627 Break this problem into two subproblems by setting (x + -1.45) equal to 1.975474627 and -1.975474627.Subproblem 1
x + -1.45 = 1.975474627 Simplifying x + -1.45 = 1.975474627 Reorder the terms: -1.45 + x = 1.975474627 Solving -1.45 + x = 1.975474627 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.45' to each side of the equation. -1.45 + 1.45 + x = 1.975474627 + 1.45 Combine like terms: -1.45 + 1.45 = 0.00 0.00 + x = 1.975474627 + 1.45 x = 1.975474627 + 1.45 Combine like terms: 1.975474627 + 1.45 = 3.425474627 x = 3.425474627 Simplifying x = 3.425474627Subproblem 2
