Simplifying 25x2 + 5x + 2 = 0 Reorder the terms: 2 + 5x + 25x2 = 0 Solving 2 + 5x + 25x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. 0.08 + 0.2x + x2 = 0 Move the constant term to the right: Add '-0.08' to each side of the equation. 0.08 + 0.2x + -0.08 + x2 = 0 + -0.08 Reorder the terms: 0.08 + -0.08 + 0.2x + x2 = 0 + -0.08 Combine like terms: 0.08 + -0.08 = 0.00 0.00 + 0.2x + x2 = 0 + -0.08 0.2x + x2 = 0 + -0.08 Combine like terms: 0 + -0.08 = -0.08 0.2x + x2 = -0.08 The x term is 0.2x. Take half its coefficient (0.1). Square it (0.01) and add it to both sides. Add '0.01' to each side of the equation. 0.2x + 0.01 + x2 = -0.08 + 0.01 Reorder the terms: 0.01 + 0.2x + x2 = -0.08 + 0.01 Combine like terms: -0.08 + 0.01 = -0.07 0.01 + 0.2x + x2 = -0.07 Factor a perfect square on the left side: (x + 0.1)(x + 0.1) = -0.07 Can't calculate square root of the right side. The solution to this equation could not be determined.
