Question

Factoriza la diferencia de cubos

1) 8x³ -64
2) 125x³- 64y{6}
3) 8a³- 27b³
4) 27a³- 27b³

Answer 1

The first one will be equal 2

Because

`( - 64)/(8) = - 8`

`x ^(3) = 8 \\`

`\sqrt[3]{ - 8} = - 2`

Oh sorry i read the question wrongly i thought you wanted the value of x

Answer 2

Explanation:

main formula used

a³-b³=(a-b)(a²+ab+b²)
