Question

factorise 8a^3 - 27b^3

Answer 1

Simplifying
8a3 + -27b3 = 0

Solving
8a3 + -27b3 = 0

Solving for variable 'a'.

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

Add '27b3' to each side of the equation.
8a3 + -27b3 + 27b3 = 0 + 27b3

Combine like terms: -27b3 + 27b3 = 0
8a3 + 0 = 0 + 27b3
8a3 = 0 + 27b3
Remove the zero:
8a3 = 27b3

Divide each side by '8'.
a3 = 3.375b3

Simplifying
a3 = 3.375b3

Combine like terms: 3.375b3 + -3.375b3 = 0.000
a3 + -3.375b3 = 0.000

The solution to this equation could not be determined.
