Simplifying (x2 + -40x + 900) = 0 Reorder the terms: (900 + -40x + x2) = 0 Remove parenthesis around (900 + -40x + x2) 900 + -40x + x2 = 0 Solving 900 + -40x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-900' to each side of the equation. 900 + -40x + -900 + x2 = 0 + -900 Reorder the terms: 900 + -900 + -40x + x2 = 0 + -900 Combine like terms: 900 + -900 = 0 0 + -40x + x2 = 0 + -900 -40x + x2 = 0 + -900 Combine like terms: 0 + -900 = -900 -40x + x2 = -900 The x term is -40x. Take half its coefficient (-20). Square it (400) and add it to both sides. Add '400' to each side of the equation. -40x + 400 + x2 = -900 + 400 Reorder the terms: 400 + -40x + x2 = -900 + 400 Combine like terms: -900 + 400 = -500 400 + -40x + x2 = -500 Factor a perfect square on the left side: (x + -20)(x + -20) = -500 Can't calculate square root of the right side. The solution to this equation could not be determined.
