Question

Factorise a'6−63a'3−64

Answer 1

$\star\:\:\:\bf\large\underline\blue{Question:-}$

• Factorise the polynomial.

$\star\:\:\:\bf\large\underline\blue{Solution:-}$

${a}^{6} - 63 {a}^{3} - 64$

${a}^{6} - 64 {a}^{3} + {a }^{3} - 64$

$= {a}^{3} ( {a}^{3} - 64) + 1( { a}^{3} - 64)$

$= ({a}^{3} + 1)( { a}^{3} - 64)$

$= (a + 1)( {a}^{2} - a + 1)(a - 4)( {a}^{2} + 4a +16)$

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• $(a + 1)( {a}^{2} - a + 1)(a - 4)( {a}^{2} + 4a +16)$
