Question

1. Solve the following using a suitable identity:
(a) (y+8)(y + 8)
​

Answer 1

Answer:

Step-by-step explanation:

(y+8)(y+8)

identity - a²+2ab+b²

y² + 2x8y+ 64

y² + 16y + 64

Hope it helps!!⚡

Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}$

To Solve:

• (y + 8)(y + 8)

Solution:

➡ (y + 8)(y + 8)

➡ (y + 8)²

➡ y² + 2(y)(8) + 8²

➡ y² + 16y + 64

Formula Used:

• (a + b)² = a² + 2ab + b²
