Solution for (3z-u)*(3z+5u)= equation:


Simplifying
(3z + -1u)(3z + 5u) = 0

Reorder the terms:
(-1u + 3z)(3z + 5u) = 0

Reorder the terms:
(-1u + 3z)(5u + 3z) = 0

Multiply (-1u + 3z) * (5u + 3z)
(-1u * (5u + 3z) + 3z * (5u + 3z)) = 0
((5u * -1u + 3z * -1u) + 3z * (5u + 3z)) = 0

Reorder the terms:
((-3uz + -5u2) + 3z * (5u + 3z)) = 0
((-3uz + -5u2) + 3z * (5u + 3z)) = 0
(-3uz + -5u2 + (5u * 3z + 3z * 3z)) = 0
(-3uz + -5u2 + (15uz + 9z2)) = 0

Reorder the terms:
(-3uz + 15uz + -5u2 + 9z2) = 0

Combine like terms: -3uz + 15uz = 12uz
(12uz + -5u2 + 9z2) = 0

Solving
12uz + -5u2 + 9z2 = 0

Solving for variable 'u'.

Factor a trinomial.
(-5u + -3z)(u + -3z) = 0

Subproblem 1

Set the factor '(-5u + -3z)' equal to zero and attempt to solve: Simplifying -5u + -3z = 0 Solving -5u + -3z = 0 Move all terms containing u to the left, all other terms to the right. Add '3z' to each side of the equation. -5u + -3z + 3z = 0 + 3z Combine like terms: -3z + 3z = 0 -5u + 0 = 0 + 3z -5u = 0 + 3z Remove the zero: -5u = 3z Divide each side by '-5'. u = -0.6z Simplifying u = -0.6z

Subproblem 2

Set the factor '(u + -3z)' equal to zero and attempt to solve: Simplifying u + -3z = 0 Solving u + -3z = 0 Move all terms containing u to the left, all other terms to the right. Add '3z' to each side of the equation. u + -3z + 3z = 0 + 3z Combine like terms: -3z + 3z = 0 u + 0 = 0 + 3z u = 0 + 3z Remove the zero: u = 3z Simplifying u = 3z

Solution

u = {-0.6z, 3z}
