Simplifying
(3z + 7)(3z + -7) = 0
Reorder the terms:
(7 + 3z)(3z + -7) = 0
Reorder the terms:
(7 + 3z)(-7 + 3z) = 0
Multiply (7 + 3z) * (-7 + 3z)
(7(-7 + 3z) + 3z * (-7 + 3z)) = 0
((-7 * 7 + 3z * 7) + 3z * (-7 + 3z)) = 0
((-49 + 21z) + 3z * (-7 + 3z)) = 0
(-49 + 21z + (-7 * 3z + 3z * 3z)) = 0
(-49 + 21z + (-21z + 9z2)) = 0
Combine like terms: 21z + -21z = 0
(-49 + 0 + 9z2) = 0
(-49 + 9z2) = 0
Solving
-49 + 9z2 = 0
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '49' to each side of the equation.
-49 + 49 + 9z2 = 0 + 49
Combine like terms: -49 + 49 = 0
0 + 9z2 = 0 + 49
9z2 = 0 + 49
Combine like terms: 0 + 49 = 49
9z2 = 49
Divide each side by '9'.
z2 = 5.444444444
Simplifying
z2 = 5.444444444
Take the square root of each side:
z = {-2.333333333, 2.333333333}
