Simplifying 63x2 + 3x + -15 = 0 Reorder the terms: -15 + 3x + 63x2 = 0 Solving -15 + 3x + 63x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '3'. 3(-5 + x + 21x2) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-5 + x + 21x2)' equal to zero and attempt to solve: Simplifying -5 + x + 21x2 = 0 Solving -5 + x + 21x2 = 0 Begin completing the square. Divide all terms by 21 the coefficient of the squared term: Divide each side by '21'. -0.2380952381 + 0.04761904762x + x2 = 0 Move the constant term to the right: Add '0.2380952381' to each side of the equation. -0.2380952381 + 0.04761904762x + 0.2380952381 + x2 = 0 + 0.2380952381 Reorder the terms: -0.2380952381 + 0.2380952381 + 0.04761904762x + x2 = 0 + 0.2380952381 Combine like terms: -0.2380952381 + 0.2380952381 = 0.0000000000 0.0000000000 + 0.04761904762x + x2 = 0 + 0.2380952381 0.04761904762x + x2 = 0 + 0.2380952381 Combine like terms: 0 + 0.2380952381 = 0.2380952381 0.04761904762x + x2 = 0.2380952381 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. 0.04761904762x + 0.25 + x2 = 0.2380952381 + 0.25 Reorder the terms: 0.25 + 0.04761904762x + x2 = 0.2380952381 + 0.25 Combine like terms: 0.2380952381 + 0.25 = 0.4880952381 0.25 + 0.04761904762x + x2 = 0.4880952381 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 0.4880952381 Calculate the square root of the right side: 0.698638131 Break this problem into two subproblems by setting (x + 0.5) equal to 0.698638131 and -0.698638131.Subproblem 1
x + 0.5 = 0.698638131 Simplifying x + 0.5 = 0.698638131 Reorder the terms: 0.5 + x = 0.698638131 Solving 0.5 + x = 0.698638131 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 0.698638131 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 0.698638131 + -0.5 x = 0.698638131 + -0.5 Combine like terms: 0.698638131 + -0.5 = 0.198638131 x = 0.198638131 Simplifying x = 0.198638131Subproblem 2
x + 0.5 = -0.698638131 Simplifying x + 0.5 = -0.698638131 Reorder the terms: 0.5 + x = -0.698638131 Solving 0.5 + x = -0.698638131 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -0.698638131 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -0.698638131 + -0.5 x = -0.698638131 + -0.5 Combine like terms: -0.698638131 + -0.5 = -1.198638131 x = -1.198638131 Simplifying x = -1.198638131Solution
