Simplifying h2 + -1h + 42 = 0 Reorder the terms: 42 + -1h + h2 = 0 Solving 42 + -1h + h2 = 0 Solving for variable 'h'. Begin completing the square. Move the constant term to the right: Add '-42' to each side of the equation. 42 + -1h + -42 + h2 = 0 + -42 Reorder the terms: 42 + -42 + -1h + h2 = 0 + -42 Combine like terms: 42 + -42 = 0 0 + -1h + h2 = 0 + -42 -1h + h2 = 0 + -42 Combine like terms: 0 + -42 = -42 -1h + h2 = -42 The h term is -1h. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1h + 0.25 + h2 = -42 + 0.25 Reorder the terms: 0.25 + -1h + h2 = -42 + 0.25 Combine like terms: -42 + 0.25 = -41.75 0.25 + -1h + h2 = -41.75 Factor a perfect square on the left side: (h + -0.5)(h + -0.5) = -41.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
