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

• Factorise ${x}^{2} + 16x + 64$

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

${x}^{2} + 16x + 64$

$= {x}^{2} + 8x + 8x + 64$

$= x(x + 8) + 8(x + 8)$

$= (x + 8)(x + 8)$

$= {(x + 8)}^{2}$

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

• ${(x + 8)}^{2}$
