Simplifying 25x2 + -4x + 6 = 0 Reorder the terms: 6 + -4x + 25x2 = 0 Solving 6 + -4x + 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'. 0.24 + -0.16x + x2 = 0 Move the constant term to the right: Add '-0.24' to each side of the equation. 0.24 + -0.16x + -0.24 + x2 = 0 + -0.24 Reorder the terms: 0.24 + -0.24 + -0.16x + x2 = 0 + -0.24 Combine like terms: 0.24 + -0.24 = 0.00 0.00 + -0.16x + x2 = 0 + -0.24 -0.16x + x2 = 0 + -0.24 Combine like terms: 0 + -0.24 = -0.24 -0.16x + x2 = -0.24 The x term is -0.16x. Take half its coefficient (-0.08). Square it (0.0064) and add it to both sides. Add '0.0064' to each side of the equation. -0.16x + 0.0064 + x2 = -0.24 + 0.0064 Reorder the terms: 0.0064 + -0.16x + x2 = -0.24 + 0.0064 Combine like terms: -0.24 + 0.0064 = -0.2336 0.0064 + -0.16x + x2 = -0.2336 Factor a perfect square on the left side: (x + -0.08)(x + -0.08) = -0.2336 Can't calculate square root of the right side. The solution to this equation could not be determined.
