Simplifying 5x2 + 19x + -720 = 0 Reorder the terms: -720 + 19x + 5x2 = 0 Solving -720 + 19x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -144 + 3.8x + x2 = 0 Move the constant term to the right: Add '144' to each side of the equation. -144 + 3.8x + 144 + x2 = 0 + 144 Reorder the terms: -144 + 144 + 3.8x + x2 = 0 + 144 Combine like terms: -144 + 144 = 0 0 + 3.8x + x2 = 0 + 144 3.8x + x2 = 0 + 144 Combine like terms: 0 + 144 = 144 3.8x + x2 = 144 The x term is 3.8x. Take half its coefficient (1.9). Square it (3.61) and add it to both sides. Add '3.61' to each side of the equation. 3.8x + 3.61 + x2 = 144 + 3.61 Reorder the terms: 3.61 + 3.8x + x2 = 144 + 3.61 Combine like terms: 144 + 3.61 = 147.61 3.61 + 3.8x + x2 = 147.61 Factor a perfect square on the left side: (x + 1.9)(x + 1.9) = 147.61 Calculate the square root of the right side: 12.149485586 Break this problem into two subproblems by setting (x + 1.9) equal to 12.149485586 and -12.149485586.Subproblem 1
x + 1.9 = 12.149485586 Simplifying x + 1.9 = 12.149485586 Reorder the terms: 1.9 + x = 12.149485586 Solving 1.9 + x = 12.149485586 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.9' to each side of the equation. 1.9 + -1.9 + x = 12.149485586 + -1.9 Combine like terms: 1.9 + -1.9 = 0.0 0.0 + x = 12.149485586 + -1.9 x = 12.149485586 + -1.9 Combine like terms: 12.149485586 + -1.9 = 10.249485586 x = 10.249485586 Simplifying x = 10.249485586Subproblem 2
x + 1.9 = -12.149485586 Simplifying x + 1.9 = -12.149485586 Reorder the terms: 1.9 + x = -12.149485586 Solving 1.9 + x = -12.149485586 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.9' to each side of the equation. 1.9 + -1.9 + x = -12.149485586 + -1.9 Combine like terms: 1.9 + -1.9 = 0.0 0.0 + x = -12.149485586 + -1.9 x = -12.149485586 + -1.9 Combine like terms: -12.149485586 + -1.9 = -14.049485586 x = -14.049485586 Simplifying x = -14.049485586Solution
The solution to the problem is based on the solutions from the subproblems. x = {10.249485586, -14.049485586}
