     \large \bf(x + 3 +  \sqrt{2} )(x + 3 -  \sqrt{2} ) \\  \\  \tiny{ \bf  \implies x \big(x + 3 -  \sqrt{2}  \big) + 3 \big(x + 3 -  \sqrt{2}  \big) +  \sqrt{2} \big(x + 3 -  \sqrt{2}  \big)} \\  \\   \tiny{ \bf \implies {x}^{2}  + 3x \cancel{ -  \sqrt{2} x} + 3x + 9  \cancel{- 3 \sqrt{2}}  \cancel{+  \sqrt{2}x} \cancel{ + 3 \sqrt{2} }-   4 } \\  \\  \small{ \bf \implies {x}^{2} + (3 + 3)x + (  9  -  4) } \\  \small{ \bf\implies  \red{{x}^{2}  + 6x + 5}}
