I need help with this and explain how to do it please!!
6x - 4z

Simplifying

(6x + -4z)(6x + 4z) = 0

Multiply (6x + -4z) * (6x + 4z)

(6x * (6x + 4z) + -4z * (6x + 4z)) = 0

((6x * 6x + 4z * 6x) + -4z * (6x + 4z)) = 0

Reorder the terms:

((24xz + 36x2) + -4z * (6x + 4z)) = 0

((24xz + 36x2) + -4z * (6x + 4z)) = 0

(24xz + 36x2 + (6x * -4z + 4z * -4z)) = 0

(24xz + 36x2 + (-24xz + -16z2)) = 0

Reorder the terms:

(24xz + -24xz + 36x2 + -16z2) = 0

Combine like terms: 24xz + -24xz = 0

(0 + 36x2 + -16z2) = 0

(36x2 + -16z2) = 0

Solving

36x2 + -16z2 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '16z2' to each side of the equation.

36x2 + -16z2 + 16z2 = 0 + 16z2

Combine like terms: -16z2 + 16z2 = 0

36x2 + 0 = 0 + 16z2

36x2 = 0 + 16z2

Remove the zero:

36x2 = 16z2

Divide each side by '36'.

x2 = 0.4444444444z2

Simplifying

x2 = 0.4444444444z2

Take the square root of each side:

x = {-0.666666667z, 0.666666667z}
