Question

( y+9) (y+9) find the products using identities​

Answer 1

Answer:

y2+18y+81

(a+b)^2 =á^2+2 ab+ b2 is the identity used

Answer 2

$\mathfrak{\huge{\underline{Solution:}}}$

$(y + 9)(y + 9)$

We know that :

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

So,

$(y + 9) ^{2}$

$( {y})^{2} + 2 \times y \times 9 + ({9})^{2}$

${y}^{2} + 18y + 81$

Hope this helps!!!❤️
