Simplifying X2 + 2xr + -1r2 = 0 Solving X2 + 2rx + -1r2 = 0 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-2rx' to each side of the equation. X2 + 2rx + -2rx + -1r2 = 0 + -2rx Combine like terms: 2rx + -2rx = 0 X2 + 0 + -1r2 = 0 + -2rx X2 + -1r2 = 0 + -2rx Remove the zero: X2 + -1r2 = -2rx Add 'r2' to each side of the equation. X2 + -1r2 + r2 = -2rx + r2 Combine like terms: -1r2 + r2 = 0 X2 + 0 = -2rx + r2 X2 = -2rx + r2 Simplifying X2 = -2rx + r2 Reorder the terms: X2 + 2rx + -1r2 = -2rx + 2rx + r2 + -1r2 Combine like terms: -2rx + 2rx = 0 X2 + 2rx + -1r2 = 0 + r2 + -1r2 X2 + 2rx + -1r2 = r2 + -1r2 Combine like terms: r2 + -1r2 = 0 X2 + 2rx + -1r2 = 0 The solution to this equation could not be determined.
