Solution for 12j=16j(j-8) equation:


Simplifying
12j = 16j(j + -8)

Reorder the terms:
12j = 16j(-8 + j)
12j = (-8 * 16j + j * 16j)
12j = (-128j + 16j2)

Solving
12j = -128j + 16j2

Solving for variable 'j'.

Combine like terms: 12j + 128j = 140j
140j + -16j2 = -128j + 16j2 + 128j + -16j2

Reorder the terms:
140j + -16j2 = -128j + 128j + 16j2 + -16j2

Combine like terms: -128j + 128j = 0
140j + -16j2 = 0 + 16j2 + -16j2
140j + -16j2 = 16j2 + -16j2

Combine like terms: 16j2 + -16j2 = 0
140j + -16j2 = 0

Factor out the Greatest Common Factor (GCF), '4j'.
4j(35 + -4j) = 0

Ignore the factor 4.

Subproblem 1

Set the factor 'j' equal to zero and attempt to solve: Simplifying j = 0 Solving j = 0 Move all terms containing j to the left, all other terms to the right. Simplifying j = 0

Subproblem 2

Set the factor '(35 + -4j)' equal to zero and attempt to solve: Simplifying 35 + -4j = 0 Solving 35 + -4j = 0 Move all terms containing j to the left, all other terms to the right. Add '-35' to each side of the equation. 35 + -35 + -4j = 0 + -35 Combine like terms: 35 + -35 = 0 0 + -4j = 0 + -35 -4j = 0 + -35 Combine like terms: 0 + -35 = -35 -4j = -35 Divide each side by '-4'. j = 8.75 Simplifying j = 8.75

Solution

j = {0, 8.75}
