Simplifying x2 + -8x + -20 = 600 Reorder the terms: -20 + -8x + x2 = 600 Solving -20 + -8x + x2 = 600 Solving for variable 'x'. Reorder the terms: -20 + -600 + -8x + x2 = 600 + -600 Combine like terms: -20 + -600 = -620 -620 + -8x + x2 = 600 + -600 Combine like terms: 600 + -600 = 0 -620 + -8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '620' to each side of the equation. -620 + -8x + 620 + x2 = 0 + 620 Reorder the terms: -620 + 620 + -8x + x2 = 0 + 620 Combine like terms: -620 + 620 = 0 0 + -8x + x2 = 0 + 620 -8x + x2 = 0 + 620 Combine like terms: 0 + 620 = 620 -8x + x2 = 620 The x term is -8x. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8x + 16 + x2 = 620 + 16 Reorder the terms: 16 + -8x + x2 = 620 + 16 Combine like terms: 620 + 16 = 636 16 + -8x + x2 = 636 Factor a perfect square on the left side: (x + -4)(x + -4) = 636 Calculate the square root of the right side: 25.219040426 Break this problem into two subproblems by setting (x + -4) equal to 25.219040426 and -25.219040426.Subproblem 1
x + -4 = 25.219040426 Simplifying x + -4 = 25.219040426 Reorder the terms: -4 + x = 25.219040426 Solving -4 + x = 25.219040426 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
