Question

factorise =x^2-6x-27​

Answer 1

Step-by-step explanation:

x²-9x+3x-27=0

x=9 x=-3

Answer 2

${\huge{\bf{\red{\underline{Solution:}}}}}$

${\bf{\blue{\underline{Given:}}}}$

${\star \: {\sf{\green{ {x}^{2} - 6x - 27 }}}}$

${\sf{\underline{\blue{Now,}}}}</p><p>$

${\implies{\bf{ {x}^{2} - 9x + 3x - 27}}}$

${\implies{\bf{ x(x - 9) + 3(x - 9)}}}$

${\implies{\bf{ (x - 9) (x + 3)}}}$

$\star \: {\bf{ \pink{ Take: }}}$

${\implies{\bf{ x - 9 = 0 \: \: \: and \: \: \: x + 3 = 0}}}$

${\implies{\bf{ x = 9 \: \: \: and \: \: \: x = - 3}}}$

${\sf{\underline{\blue{hence \: the \: value \: of \: x = 9,3}}}}</p><p>$
