Simplifying (3v2 + -7v + 5) + -1(2v2 + 3v + -7) = 0 Reorder the terms: (5 + -7v + 3v2) + -1(2v2 + 3v + -7) = 0 Remove parenthesis around (5 + -7v + 3v2) 5 + -7v + 3v2 + -1(2v2 + 3v + -7) = 0 Reorder the terms: 5 + -7v + 3v2 + -1(-7 + 3v + 2v2) = 0 5 + -7v + 3v2 + (-7 * -1 + 3v * -1 + 2v2 * -1) = 0 5 + -7v + 3v2 + (7 + -3v + -2v2) = 0 Reorder the terms: 5 + 7 + -7v + -3v + 3v2 + -2v2 = 0 Combine like terms: 5 + 7 = 12 12 + -7v + -3v + 3v2 + -2v2 = 0 Combine like terms: -7v + -3v = -10v 12 + -10v + 3v2 + -2v2 = 0 Combine like terms: 3v2 + -2v2 = 1v2 12 + -10v + 1v2 = 0 Solving 12 + -10v + 1v2 = 0 Solving for variable 'v'. Begin completing the square. Move the constant term to the right: Add '-12' to each side of the equation. 12 + -10v + -12 + v2 = 0 + -12 Reorder the terms: 12 + -12 + -10v + v2 = 0 + -12 Combine like terms: 12 + -12 = 0 0 + -10v + v2 = 0 + -12 -10v + v2 = 0 + -12 Combine like terms: 0 + -12 = -12 -10v + v2 = -12 The v term is -10v. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10v + 25 + v2 = -12 + 25 Reorder the terms: 25 + -10v + v2 = -12 + 25 Combine like terms: -12 + 25 = 13 25 + -10v + v2 = 13 Factor a perfect square on the left side: (v + -5)(v + -5) = 13 Calculate the square root of the right side: 3.605551275 Break this problem into two subproblems by setting (v + -5) equal to 3.605551275 and -3.605551275.Subproblem 1
v + -5 = 3.605551275 Simplifying v + -5 = 3.605551275 Reorder the terms: -5 + v = 3.605551275 Solving -5 + v = 3.605551275 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + v = 3.605551275 + 5 Combine like terms: -5 + 5 = 0 0 + v = 3.605551275 + 5 v = 3.605551275 + 5 Combine like terms: 3.605551275 + 5 = 8.605551275 v = 8.605551275 Simplifying v = 8.605551275Subproblem 2
v + -5 = -3.605551275 Simplifying v + -5 = -3.605551275 Reorder the terms: -5 + v = -3.605551275 Solving -5 + v = -3.605551275 Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + v = -3.605551275 + 5 Combine like terms: -5 + 5 = 0 0 + v = -3.605551275 + 5 v = -3.605551275 + 5 Combine like terms: -3.605551275 + 5 = 1.394448725 v = 1.394448725 Simplifying v = 1.394448725Solution
