Simplifying 5X2 + 98X + -98 = 0 Reorder the terms: -98 + 98X + 5X2 = 0 Solving -98 + 98X + 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'. -19.6 + 19.6X + X2 = 0 Move the constant term to the right: Add '19.6' to each side of the equation. -19.6 + 19.6X + 19.6 + X2 = 0 + 19.6 Reorder the terms: -19.6 + 19.6 + 19.6X + X2 = 0 + 19.6 Combine like terms: -19.6 + 19.6 = 0.0 0.0 + 19.6X + X2 = 0 + 19.6 19.6X + X2 = 0 + 19.6 Combine like terms: 0 + 19.6 = 19.6 19.6X + X2 = 19.6 The X term is 19.6X. Take half its coefficient (9.8). Square it (96.04) and add it to both sides. Add '96.04' to each side of the equation. 19.6X + 96.04 + X2 = 19.6 + 96.04 Reorder the terms: 96.04 + 19.6X + X2 = 19.6 + 96.04 Combine like terms: 19.6 + 96.04 = 115.64 96.04 + 19.6X + X2 = 115.64 Factor a perfect square on the left side: (X + 9.8)(X + 9.8) = 115.64 Calculate the square root of the right side: 10.753604047 Break this problem into two subproblems by setting (X + 9.8) equal to 10.753604047 and -10.753604047.Subproblem 1
X + 9.8 = 10.753604047 Simplifying X + 9.8 = 10.753604047 Reorder the terms: 9.8 + X = 10.753604047 Solving 9.8 + X = 10.753604047 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-9.8' to each side of the equation. 9.8 + -9.8 + X = 10.753604047 + -9.8 Combine like terms: 9.8 + -9.8 = 0.0 0.0 + X = 10.753604047 + -9.8 X = 10.753604047 + -9.8 Combine like terms: 10.753604047 + -9.8 = 0.953604047 X = 0.953604047 Simplifying X = 0.953604047Subproblem 2
X + 9.8 = -10.753604047 Simplifying X + 9.8 = -10.753604047 Reorder the terms: 9.8 + X = -10.753604047 Solving 9.8 + X = -10.753604047 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-9.8' to each side of the equation. 9.8 + -9.8 + X = -10.753604047 + -9.8 Combine like terms: 9.8 + -9.8 = 0.0 0.0 + X = -10.753604047 + -9.8 X = -10.753604047 + -9.8 Combine like terms: -10.753604047 + -9.8 = -20.553604047 X = -20.553604047 Simplifying X = -20.553604047Solution
