Simplifying 16x2 + -30x + 2 = 0 Reorder the terms: 2 + -30x + 16x2 = 0 Solving 2 + -30x + 16x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(1 + -15x + 8x2) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(1 + -15x + 8x2)' equal to zero and attempt to solve: Simplifying 1 + -15x + 8x2 = 0 Solving 1 + -15x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. 0.125 + -1.875x + x2 = 0 Move the constant term to the right: Add '-0.125' to each side of the equation. 0.125 + -1.875x + -0.125 + x2 = 0 + -0.125 Reorder the terms: 0.125 + -0.125 + -1.875x + x2 = 0 + -0.125 Combine like terms: 0.125 + -0.125 = 0.000 0.000 + -1.875x + x2 = 0 + -0.125 -1.875x + x2 = 0 + -0.125 Combine like terms: 0 + -0.125 = -0.125 -1.875x + x2 = -0.125 The x term is -1.875x. Take half its coefficient (-0.9375). Square it (0.87890625) and add it to both sides. Add '0.87890625' to each side of the equation. -1.875x + 0.87890625 + x2 = -0.125 + 0.87890625 Reorder the terms: 0.87890625 + -1.875x + x2 = -0.125 + 0.87890625 Combine like terms: -0.125 + 0.87890625 = 0.75390625 0.87890625 + -1.875x + x2 = 0.75390625 Factor a perfect square on the left side: (x + -0.9375)(x + -0.9375) = 0.75390625 Calculate the square root of the right side: 0.868277749 Break this problem into two subproblems by setting (x + -0.9375) equal to 0.868277749 and -0.868277749.Subproblem 1
x + -0.9375 = 0.868277749 Simplifying x + -0.9375 = 0.868277749 Reorder the terms: -0.9375 + x = 0.868277749 Solving -0.9375 + x = 0.868277749 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.9375' to each side of the equation. -0.9375 + 0.9375 + x = 0.868277749 + 0.9375 Combine like terms: -0.9375 + 0.9375 = 0.0000 0.0000 + x = 0.868277749 + 0.9375 x = 0.868277749 + 0.9375 Combine like terms: 0.868277749 + 0.9375 = 1.805777749 x = 1.805777749 Simplifying x = 1.805777749Subproblem 2
x + -0.9375 = -0.868277749 Simplifying x + -0.9375 = -0.868277749 Reorder the terms: -0.9375 + x = -0.868277749 Solving -0.9375 + x = -0.868277749 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.9375' to each side of the equation. -0.9375 + 0.9375 + x = -0.868277749 + 0.9375 Combine like terms: -0.9375 + 0.9375 = 0.0000 0.0000 + x = -0.868277749 + 0.9375 x = -0.868277749 + 0.9375 Combine like terms: -0.868277749 + 0.9375 = 0.069222251 x = 0.069222251 Simplifying x = 0.069222251Solution
