Simplifying (y + -4)(y + -4) = 18 Reorder the terms: (-4 + y)(y + -4) = 18 Reorder the terms: (-4 + y)(-4 + y) = 18 Multiply (-4 + y) * (-4 + y) (-4(-4 + y) + y(-4 + y)) = 18 ((-4 * -4 + y * -4) + y(-4 + y)) = 18 ((16 + -4y) + y(-4 + y)) = 18 (16 + -4y + (-4 * y + y * y)) = 18 (16 + -4y + (-4y + y2)) = 18 Combine like terms: -4y + -4y = -8y (16 + -8y + y2) = 18 Solving 16 + -8y + y2 = 18 Solving for variable 'y'. Reorder the terms: 16 + -18 + -8y + y2 = 18 + -18 Combine like terms: 16 + -18 = -2 -2 + -8y + y2 = 18 + -18 Combine like terms: 18 + -18 = 0 -2 + -8y + y2 = 0 Begin completing the square. Move the constant term to the right: Add '2' to each side of the equation. -2 + -8y + 2 + y2 = 0 + 2 Reorder the terms: -2 + 2 + -8y + y2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -8y + y2 = 0 + 2 -8y + y2 = 0 + 2 Combine like terms: 0 + 2 = 2 -8y + y2 = 2 The y term is -8y. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8y + 16 + y2 = 2 + 16 Reorder the terms: 16 + -8y + y2 = 2 + 16 Combine like terms: 2 + 16 = 18 16 + -8y + y2 = 18 Factor a perfect square on the left side: (y + -4)(y + -4) = 18 Calculate the square root of the right side: 4.242640687 Break this problem into two subproblems by setting (y + -4) equal to 4.242640687 and -4.242640687.Subproblem 1
y + -4 = 4.242640687 Simplifying y + -4 = 4.242640687 Reorder the terms: -4 + y = 4.242640687 Solving -4 + y = 4.242640687 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + y = 4.242640687 + 4 Combine like terms: -4 + 4 = 0 0 + y = 4.242640687 + 4 y = 4.242640687 + 4 Combine like terms: 4.242640687 + 4 = 8.242640687 y = 8.242640687 Simplifying y = 8.242640687Subproblem 2
y + -4 = -4.242640687 Simplifying y + -4 = -4.242640687 Reorder the terms: -4 + y = -4.242640687 Solving -4 + y = -4.242640687 Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + y = -4.242640687 + 4 Combine like terms: -4 + 4 = 0 0 + y = -4.242640687 + 4 y = -4.242640687 + 4 Combine like terms: -4.242640687 + 4 = -0.242640687 y = -0.242640687 Simplifying y = -0.242640687Solution
