Simplifying 25X2 + -30X + 9 = 125 Reorder the terms: 9 + -30X + 25X2 = 125 Solving 9 + -30X + 25X2 = 125 Solving for variable 'X'. Reorder the terms: 9 + -125 + -30X + 25X2 = 125 + -125 Combine like terms: 9 + -125 = -116 -116 + -30X + 25X2 = 125 + -125 Combine like terms: 125 + -125 = 0 -116 + -30X + 25X2 = 0 Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. -4.64 + -1.2X + X2 = 0 Move the constant term to the right: Add '4.64' to each side of the equation. -4.64 + -1.2X + 4.64 + X2 = 0 + 4.64 Reorder the terms: -4.64 + 4.64 + -1.2X + X2 = 0 + 4.64 Combine like terms: -4.64 + 4.64 = 0.00 0.00 + -1.2X + X2 = 0 + 4.64 -1.2X + X2 = 0 + 4.64 Combine like terms: 0 + 4.64 = 4.64 -1.2X + X2 = 4.64 The X term is -1.2X. Take half its coefficient (-0.6). Square it (0.36) and add it to both sides. Add '0.36' to each side of the equation. -1.2X + 0.36 + X2 = 4.64 + 0.36 Reorder the terms: 0.36 + -1.2X + X2 = 4.64 + 0.36 Combine like terms: 4.64 + 0.36 = 5 0.36 + -1.2X + X2 = 5 Factor a perfect square on the left side: (X + -0.6)(X + -0.6) = 5 Calculate the square root of the right side: 2.236067978 Break this problem into two subproblems by setting (X + -0.6) equal to 2.236067978 and -2.236067978.Subproblem 1
X + -0.6 = 2.236067978 Simplifying X + -0.6 = 2.236067978 Reorder the terms: -0.6 + X = 2.236067978 Solving -0.6 + X = 2.236067978 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '0.6' to each side of the equation. -0.6 + 0.6 + X = 2.236067978 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + X = 2.236067978 + 0.6 X = 2.236067978 + 0.6 Combine like terms: 2.236067978 + 0.6 = 2.836067978 X = 2.836067978 Simplifying X = 2.836067978Subproblem 2
X + -0.6 = -2.236067978 Simplifying X + -0.6 = -2.236067978 Reorder the terms: -0.6 + X = -2.236067978 Solving -0.6 + X = -2.236067978 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '0.6' to each side of the equation. -0.6 + 0.6 + X = -2.236067978 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + X = -2.236067978 + 0.6 X = -2.236067978 + 0.6 Combine like terms: -2.236067978 + 0.6 = -1.636067978 X = -1.636067978 Simplifying X = -1.636067978Solution
