Solution for 2(v+8)=-4(4v-8)8v equation:


Simplifying
2(v + 8) = -4(4v + -8) * 8v

Reorder the terms:
2(8 + v) = -4(4v + -8) * 8v
(8 * 2 + v * 2) = -4(4v + -8) * 8v
(16 + 2v) = -4(4v + -8) * 8v

Reorder the terms:
16 + 2v = -4(-8 + 4v) * 8v

Reorder the terms for easier multiplication:
16 + 2v = -4 * 8v(-8 + 4v)

Multiply -4 * 8
16 + 2v = -32v(-8 + 4v)
16 + 2v = (-8 * -32v + 4v * -32v)
16 + 2v = (256v + -128v2)

Solving
16 + 2v = 256v + -128v2

Solving for variable 'v'.

Combine like terms: 2v + -256v = -254v
16 + -254v + 128v2 = 256v + -128v2 + -256v + 128v2

Reorder the terms:
16 + -254v + 128v2 = 256v + -256v + -128v2 + 128v2

Combine like terms: 256v + -256v = 0
16 + -254v + 128v2 = 0 + -128v2 + 128v2
16 + -254v + 128v2 = -128v2 + 128v2

Combine like terms: -128v2 + 128v2 = 0
16 + -254v + 128v2 = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(8 + -127v + 64v2) = 0

Ignore the factor 2.

Subproblem 1

Set the factor '(8 + -127v + 64v2)' equal to zero and attempt to solve: Simplifying 8 + -127v + 64v2 = 0 Solving 8 + -127v + 64v2 = 0 Begin completing the square. Divide all terms by 64 the coefficient of the squared term: Divide each side by '64'. 0.125 + -1.984375v + v2 = 0 Move the constant term to the right: Add '-0.125' to each side of the equation. 0.125 + -1.984375v + -0.125 + v2 = 0 + -0.125 Reorder the terms: 0.125 + -0.125 + -1.984375v + v2 = 0 + -0.125 Combine like terms: 0.125 + -0.125 = 0.000 0.000 + -1.984375v + v2 = 0 + -0.125 -1.984375v + v2 = 0 + -0.125 Combine like terms: 0 + -0.125 = -0.125 -1.984375v + v2 = -0.125 The v term is -1.984375v.
