Simplifying x2 + 13x + 4 = 0 Reorder the terms: 4 + 13x + x2 = 0 Solving 4 + 13x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + 13x + -4 + x2 = 0 + -4 Reorder the terms: 4 + -4 + 13x + x2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 13x + x2 = 0 + -4 13x + x2 = 0 + -4 Combine like terms: 0 + -4 = -4 13x + x2 = -4 The x term is 13x. Take half its coefficient (6.5). Square it (42.25) and add it to both sides. Add '42.25' to each side of the equation. 13x + 42.25 + x2 = -4 + 42.25 Reorder the terms: 42.25 + 13x + x2 = -4 + 42.25 Combine like terms: -4 + 42.25 = 38.25 42.25 + 13x + x2 = 38.25 Factor a perfect square on the left side: (x + 6.5)(x + 6.5) = 38.25 Calculate the square root of the right side: 6.184658438 Break this problem into two subproblems by setting (x + 6.5) equal to 6.184658438 and -6.184658438.Subproblem 1
x + 6.5 = 6.184658438 Simplifying x + 6.5 = 6.184658438 Reorder the terms: 6.5 + x = 6.184658438 Solving 6.5 + x = 6.184658438 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.5' to each side of the equation. 6.5 + -6.5 + x = 6.184658438 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + x = 6.184658438 + -6.5 x = 6.184658438 + -6.5 Combine like terms: 6.184658438 + -6.5 = -0.315341562 x = -0.315341562 Simplifying x = -0.315341562Subproblem 2
x + 6.5 = -6.184658438 Simplifying x + 6.5 = -6.184658438 Reorder the terms: 6.5 + x = -6.184658438 Solving 6.5 + x = -6.184658438 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.5' to each side of the equation. 6.5 + -6.5 + x = -6.184658438 + -6.5 Combine like terms: 6.5 + -6.5 = 0.0 0.0 + x = -6.184658438 + -6.5 x = -6.184658438 + -6.5 Combine like terms: -6.184658438 + -6.5 = -12.684658438 x = -12.684658438 Simplifying x = -12.684658438Solution
