Question

division of algebra (297)square using identities

Answer 1

✔✔ Answer ✔✔

⭕ (297)^2
✏ (300 - 3)^2
✏ (300)^2 + (3)^2 - 2(300)(3)
✏ 90000 + 9 - 1800
✏ 88209

Answer 2

********************

We know the algebraic identity:

(x-y)² = x² -2xy + y²

*********************

Now ,

(297)²

= (300-3)²

= (300)² -2×300×3 + 3²

= 90000 - 1800 + 9

= 88209
