Simplifying 10x2 + 89x + -9 = 4 Reorder the terms: -9 + 89x + 10x2 = 4 Solving -9 + 89x + 10x2 = 4 Solving for variable 'x'. Reorder the terms: -9 + -4 + 89x + 10x2 = 4 + -4 Combine like terms: -9 + -4 = -13 -13 + 89x + 10x2 = 4 + -4 Combine like terms: 4 + -4 = 0 -13 + 89x + 10x2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -1.3 + 8.9x + x2 = 0 Move the constant term to the right: Add '1.3' to each side of the equation. -1.3 + 8.9x + 1.3 + x2 = 0 + 1.3 Reorder the terms: -1.3 + 1.3 + 8.9x + x2 = 0 + 1.3 Combine like terms: -1.3 + 1.3 = 0.0 0.0 + 8.9x + x2 = 0 + 1.3 8.9x + x2 = 0 + 1.3 Combine like terms: 0 + 1.3 = 1.3 8.9x + x2 = 1.3 The x term is 8.9x. Take half its coefficient (4.45). Square it (19.8025) and add it to both sides. Add '19.8025' to each side of the equation. 8.9x + 19.8025 + x2 = 1.3 + 19.8025 Reorder the terms: 19.8025 + 8.9x + x2 = 1.3 + 19.8025 Combine like terms: 1.3 + 19.8025 = 21.1025 19.8025 + 8.9x + x2 = 21.1025 Factor a perfect square on the left side: (x + 4.45)(x + 4.45) = 21.1025 Calculate the square root of the right side: 4.593745748 Break this problem into two subproblems by setting (x + 4.45) equal to 4.593745748 and -4.593745748.Subproblem 1
x + 4.45 = 4.593745748 Simplifying x + 4.45 = 4.593745748 Reorder the terms: 4.45 + x = 4.593745748 Solving 4.45 + x = 4.593745748 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.45' to each side of the equation. 4.45 + -4.45 + x = 4.593745748 + -4.45 Combine like terms: 4.45 + -4.45 = 0.00 0.00 + x = 4.593745748 + -4.45 x = 4.593745748 + -4.45 Combine like terms: 4.593745748 + -4.45 = 0.143745748 x = 0.143745748 Simplifying x = 0.143745748Subproblem 2
x + 4.45 = -4.593745748 Simplifying x + 4.45 = -4.593745748 Reorder the terms: 4.45 + x = -4.593745748 Solving 4.45 + x = -4.593745748 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.45' to each side of the equation. 4.45 + -4.45 + x = -4.593745748 + -4.45 Combine like terms: 4.45 + -4.45 = 0.00 0.00 + x = -4.593745748 + -4.45 x = -4.593745748 + -4.45 Combine like terms: -4.593745748 + -4.45 = -9.043745748 x = -9.043745748 Simplifying x = -9.043745748Solution
