Question

factorise 27a^3 - 2 root 2b^3​

Answer 1

Answer:

$27 {a}^{3} - 2 \sqrt{2} {b}^{3} =$

$(3a) {}^{3} - ( \sqrt{2} b) {}^{3} =$

$(3a - \sqrt{2} b)((3a) {}^{2} + 3a \times \sqrt{2} b + ( \sqrt{2} b) {}^{2} ) =$

$(3a - \sqrt{2} b)(9 {a}^{2} + 3 \sqrt{2} ab + 2 {b}^{2} )$

Step-by-step explanation:

${x}^{3} - {y}^{3} = (x - y)( {x}^{2} + xy + {y}^{2} )$
