Simplifying 16x2 + 16x + 4 = 3 Reorder the terms: 4 + 16x + 16x2 = 3 Solving 4 + 16x + 16x2 = 3 Solving for variable 'x'. Reorder the terms: 4 + -3 + 16x + 16x2 = 3 + -3 Combine like terms: 4 + -3 = 1 1 + 16x + 16x2 = 3 + -3 Combine like terms: 3 + -3 = 0 1 + 16x + 16x2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. 0.0625 + x + x2 = 0 Move the constant term to the right: Add '-0.0625' to each side of the equation. 0.0625 + x + -0.0625 + x2 = 0 + -0.0625 Reorder the terms: 0.0625 + -0.0625 + x + x2 = 0 + -0.0625 Combine like terms: 0.0625 + -0.0625 = 0.0000 0.0000 + x + x2 = 0 + -0.0625 x + x2 = 0 + -0.0625 Combine like terms: 0 + -0.0625 = -0.0625 x + x2 = -0.0625 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. + 0.25 + x2 = -0.0625 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = -0.0625 + 0.25 Combine like terms: -0.0625 + 0.25 = 0.1875 1.25 + x2 = 0.1875 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 0.1875 Calculate the square root of the right side: 0.433012702 Break this problem into two subproblems by setting (x + 0.5) equal to 0.433012702 and -0.433012702.Subproblem 1
x + 0.5 = 0.433012702 Simplifying x + 0.5 = 0.433012702 Reorder the terms: 0.5 + x = 0.433012702 Solving 0.5 + x = 0.433012702 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 = 0.433012702 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 0.433012702 + -0.5 x = 0.433012702 + -0.5 Combine like terms: 0.433012702 + -0.5 = -0.066987298 x = -0.066987298 Simplifying x = -0.066987298Subproblem 2
x + 0.5 = -0.433012702 Simplifying x + 0.5 = -0.433012702 Reorder the terms: 0.5 + x = -0.433012702 Solving 0.5 + x = -0.433012702 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 = -0.433012702 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -0.433012702 + -0.5 x = -0.433012702 + -0.5 Combine like terms: -0.433012702 + -0.5 = -0.933012702 x = -0.933012702 Simplifying x = -0.933012702Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.066987298, -0.933012702}
