Simplifying b2 + 10 = 4b Reorder the terms: 10 + b2 = 4b Solving 10 + b2 = 4b Solving for variable 'b'. Reorder the terms: 10 + -4b + b2 = 4b + -4b Combine like terms: 4b + -4b = 0 10 + -4b + b2 = 0 Begin completing the square. Move the constant term to the right: Add '-10' to each side of the equation. 10 + -4b + -10 + b2 = 0 + -10 Reorder the terms: 10 + -10 + -4b + b2 = 0 + -10 Combine like terms: 10 + -10 = 0 0 + -4b + b2 = 0 + -10 -4b + b2 = 0 + -10 Combine like terms: 0 + -10 = -10 -4b + b2 = -10 The b term is -4b. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4b + 4 + b2 = -10 + 4 Reorder the terms: 4 + -4b + b2 = -10 + 4 Combine like terms: -10 + 4 = -6 4 + -4b + b2 = -6 Factor a perfect square on the left side: (b + -2)(b + -2) = -6 Can't calculate square root of the right side. The solution to this equation could not be determined.
