Question

216x^3 + 1/125 factorise it

Answer 1

$= 216 {x}^{3} + \frac{1}{125} \\ \\ using \: {x}^{3} + {y}^{3} = (x + y)( {x}^{2} + {y}^{2} - xy) \\ \\ = {(6x)}^{3} + {( \frac{1}{5} )}^{3} \\ \\ = (6x + \frac{1}{5})( \: {(6x)}^{2} + ( { \frac{1}{5} })^{2} - 6x \times \frac{1}{5} ) \\ \\ = (6x + \frac{1}{5} )(36 {x}^{2} + \frac{1}{25} - \frac{6x}{5} )$
