Simplifying x2 + 4x + 21 = 10x Reorder the terms: 21 + 4x + x2 = 10x Solving 21 + 4x + x2 = 10x Solving for variable 'x'. Reorder the terms: 21 + 4x + -10x + x2 = 10x + -10x Combine like terms: 4x + -10x = -6x 21 + -6x + x2 = 10x + -10x Combine like terms: 10x + -10x = 0 21 + -6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-21' to each side of the equation. 21 + -6x + -21 + x2 = 0 + -21 Reorder the terms: 21 + -21 + -6x + x2 = 0 + -21 Combine like terms: 21 + -21 = 0 0 + -6x + x2 = 0 + -21 -6x + x2 = 0 + -21 Combine like terms: 0 + -21 = -21 -6x + x2 = -21 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = -21 + 9 Reorder the terms: 9 + -6x + x2 = -21 + 9 Combine like terms: -21 + 9 = -12 9 + -6x + x2 = -12 Factor a perfect square on the left side: (x + -3)(x + -3) = -12 Can't calculate square root of the right side. The solution to this equation could not be determined.
