Answer 1

Answer:

(x-6)(x-6)

Step-by-step explanation:

   (*)36

-6         -6

   (+)-12

= (x-6)(x-6)

= value of x is 6,6

Answer 2

Step-by-step explanation:

$\bf \large \underline{\red{Question : - }}$

• $\sf \to \: factorise \: {b}^{2} + 12b + 36 </li><li>$

$\bf \large \underline{\red{given : - }}$

• $\sf \to \: \: {b}^{2} + 12b + 36 </li><li>$

$\bf \large \underline{\red{To \: Find: - }}$

• $\text{ \sf \: Find the factory }$

$\bf \large \underline{\red{solution: - }}$

$\sf \large \underline{\red{first \: method}} \: \huge \dag \:$

$\sf \to \: \: {b}^{2} + 12b + 36 \\ \\ \sf \to \: \: {b}^{2} + 6b + 6b + 36 \\ \\ \sf \to \: \: b( b + 6) + 6(b + 6) \\ \\ \sf \to \: \: (b + 6)(b + 6)\\\\\\</p><p>$

$\sf \large \underline{\red{second\: method}} \: \huge \dag \:$

$\sf \to \: \: {b}^{2} + 12b + 36 \\ \\ </p><p> \sf \to \: \: {b}^{2} + 2 \times (6)(b) + {6}^{2} \\ \\ \sf \to \: \: {(b + 6)}^{2} \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \therefore \sf \boxed{ \sf \red{( {a + b})^{2} = {a}^{2} + {b}^{2} + 2ab }}\: \\ \\ \sf \to \: \: (b + 6)(b + 6)$
