अध्याय 11 Fundamental Concepts (Including Fundamental Operations)
Exercise 11 (A) | Q 6.2

Identify the term, their coefficients for the following expression:

x² + x + 1

Write numerical co-efficient of the following: y

Write numerical co-efficient of the following: – 9a²b³

Simplify: (p – 2q) – (3q – r)

Simplify: `"p"^2 - ["x"^2 - {"x"^2 - ("q"^2 - bar("x"^2 - "q"^2)) - "2y"^2}]`

Simplify: `10 – {4"a" – (7 – bar ("a" - 5) - (5"a" - bar(1 + "a")))`

To add two like terms, its coefficients can be added
