Answer 2

$\huge\pink{\underline{\boxed{\mathbb{ANSWER }}}}$

These are the answers of the question which you had asked me.

(i)

${(x - 2y)}^{2} + {(2x + y)}^{2}$

${x}^{2} - 4xy + 4 {y}^{2} + (4 {x}^{2} + 4xy + {y}^{2} )$

${x}^{2} - 4xy + 4 {y}^{2} + 4 {x}^{2} + 4xy + {y}^{2}$

$5 {x}^{2} + 5 {y}^{2}$

$5( {x}^{2} + {y}^{2} )$

(ii)

${(a + 3b)}^{2} + {(a - b)}^{2}$

${a}^{2} + 6ab + 9 {b}^{2} + ( {a}^{2} - 2ab + {b}^{2})$

${a}^{2} + 6ab + 9 {b}^{2} + {a}^{2} - 2ab + {b}^{2}$

$2 {a}^{2} + 10 {b}^{2} + 4ab$

divide by "2"

${a}^{2} + 5 {b}^{2} + 2ab$

(iii)

${(s + t)}^{2} + {(s + t)}^{2} + st$

${s}^{2} + 2st + {t}^{2} + {s}^{2} + 2st + {t}^{2} + st$

$2 {s}^{2} + 2 {t}^{2} + 5st$
