Question

factorise: 216-125x³​

Answer 1

125x3=5x and 216=63.

We can use the sum of cubes to factor (125x3+216) . (a3+b3)=(a+b)(a2−ab+b2).

Answer 2

216−125x³

6³−5x³

Now put formula,

( a - b)(a²+b²+ab)

( 6 - 5x)( 6²+( 5x )²+5x×6 )

( 6 - 5x)( 6²+( 5x )²+30x )

( 6 - 5x)(( 5x )² + 30x + 36 )
