Simplifying (v + -7)(v + 7) = x Reorder the terms: (-7 + v)(v + 7) = x Reorder the terms: (-7 + v)(7 + v) = x Multiply (-7 + v) * (7 + v) (-7(7 + v) + v(7 + v)) = x ((7 * -7 + v * -7) + v(7 + v)) = x ((-49 + -7v) + v(7 + v)) = x (-49 + -7v + (7 * v + v * v)) = x (-49 + -7v + (7v + v2)) = x Combine like terms: -7v + 7v = 0 (-49 + 0 + v2) = x (-49 + v2) = x Solving -49 + v2 = x Solving for variable 'v'. Move all terms containing v to the left, all other terms to the right. Add '49' to each side of the equation. -49 + 49 + v2 = 49 + x Combine like terms: -49 + 49 = 0 0 + v2 = 49 + x v2 = 49 + x Simplifying v2 = 49 + x Reorder the terms: -49 + v2 + -1x = 49 + x + -49 + -1x Reorder the terms: -49 + v2 + -1x = 49 + -49 + x + -1x Combine like terms: 49 + -49 = 0 -49 + v2 + -1x = 0 + x + -1x -49 + v2 + -1x = x + -1x Combine like terms: x + -1x = 0 -49 + v2 + -1x = 0 The solution to this equation could not be determined.
