Answer 2

$\huge \fbox \green{Answer:}$

$\sf \colorbox{pink} {Ans . 26}$

$\sf \colorbox{god} {1. Pairing And Dividing }$

$\sf \colorbox{god} {2. \: Next \: Pair↓}$

$3. \: 1 \times 2 = 2;$

$\: \: 22 \times 2 = 44$

$4. \: 56 - 44 = 12;$

$Next \: Pair \: ↓↓12 \times 2 = 24;$

$⇒245 \times 5 = 1225 - 1225 = 0$

$\sf \colorbox{pink} {Ans. 27}$

Given:

${x}^{2} + xy + 8x + 8y$

To find: Factorie

$\huge \fbox \pink{Solution: }$

$⇒ {x}^{2} + xy + 8x + 8y$

$= x(x + y) + 8(x + y)$

$= (x + 8)(x + y)$

$\sf \colorbox{lightgreen} {Ans. 28 This question is very easy, so do it yourself.}$

$\sf \colorbox{pink} {Ans. 29 }$

Given:

$25 {m}^{2} + 30 m + 9$

To find Factorie:

$⇒25 {m}^{2} + 30m + 9$

$= (5m {)}^{2} + 2 \times 5m \times 3 + (3 {)}^{2}$

$[using \: identity \: {a}^{2} + 2ab + {b}^{2} = (a + b {)}^{2} ]$

$= (5m + 3 {)}^{2}$
