Answer 1

$\sf \bf \huge {\boxed {\mathbb {QUESTION}}}$

$\sf \bf {( 4 +5x)}^{2}$

$\sf \bf \huge {\boxed {\mathbb {ANSWER}}}$

$\sf \bf \implies {( 4 +5x)}^{2}$

$\sf \bf \implies {(4+5x)}^{2}={(4)}^{2}+2(4)(5x)+{5x}^{2}$

$\implies {\boxed {\color {red} {\sf \bf {(4+5x)}^{2}=16+40x+25{x}^{2}}}}$

$\sf \bf {(a+b)}^{2}={a}^{2}+2ab+{b}^{2}$

$\sf \bf {(a-b)}^{2}={a}^{2}-2ab+{b}^{2}$

$\sf \bf (a+b) (a-b) ={a}^{2}-{b}^{2}$

$\implies{\green{{(4x+5x^2)}}}$

$\implies{\red{{(4 +{5x}^{2}) = ( {4}^{2} ) + 2(4)(5x) + {5x}^{2} }}}$

$\implies{\blue{(4x + {5x}^{2}) = 16 + 40x + {25}^{2} }}$
