Simplifying 2.71 = x(0.970 + -1x) 2.71 = (0.970 * x + -1x * x) 2.71 = (0.970x + -1x2) Solving 2.71 = 0.970x + -1x2 Solving for variable 'x'. Reorder the terms: 2.71 + -0.970x + x2 = 0.970x + -0.970x + -1x2 + x2 Combine like terms: 0.970x + -0.970x = 0.000 2.71 + -0.970x + x2 = 0.000 + -1x2 + x2 2.71 + -0.970x + x2 = -1x2 + x2 Combine like terms: -1x2 + x2 = 0 2.71 + -0.970x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-2.71' to each side of the equation. 2.71 + -0.970x + -2.71 + x2 = 0 + -2.71 Reorder the terms: 2.71 + -2.71 + -0.970x + x2 = 0 + -2.71 Combine like terms: 2.71 + -2.71 = 0.00 0.00 + -0.970x + x2 = 0 + -2.71 -0.970x + x2 = 0 + -2.71 Combine like terms: 0 + -2.71 = -2.71 -0.970x + x2 = -2.71 The x term is -0.970x. Take half its coefficient (-0.485). Square it (0.235225) and add it to both sides. Add '0.235225' to each side of the equation. -0.970x + 0.235225 + x2 = -2.71 + 0.235225 Reorder the terms: 0.235225 + -0.970x + x2 = -2.71 + 0.235225 Combine like terms: -2.71 + 0.235225 = -2.474775 0.235225 + -0.970x + x2 = -2.474775 Factor a perfect square on the left side: (x + -0.485)(x + -0.485) = -2.474775 Can't calculate square root of the right side. The solution to this equation could not be determined.
