Question

factorise x² + 3x + ax + 3a

Answer 1

$\huge{ \underline{ \overline{ \mid{ \mathfrak{ \purple{ \: \: SOLUTION \: \: } \mid}}}}}$

$\huge{\underline{ \mathfrak{ \: \: To \: \: Factorise : \mapsto \: }}}</p><p></p><p>$

$\: \: \: \: \: \sf{ \red{x {}^{2} + 3x + ax + 3a }}\\ \\ \sf{ \green{= x(x + 3) + a(x + 3)} }\\ \\ \sf{ \pink{= (x + a)(x + 3)}}$

$\huge{ \underline{ \mathfrak{ \: \: Verification : \mapsto \: \: }}}$

$\: \: \: \: \: \tt{ \blue{(x + a)(x + 3)}} \\ \\ \tt{ \pink{= x(x + 3) + a(x + 3)}} \\ \\ \tt{ \red{= x {}^{2} + 3x + ax + 3a}}$

Answer 2

Answer:

x(x+3) + a (x+3)

(x+3) ( x+a)

Hope this will help.
