Exercise 11 (B) | Q 3.1

Identify the terms, their coefficients for the following expressions.

`x/2 + y/2 - xy`

In -5x³y²z⁴ ; write the coefficient of y² Also, write the degree of the given algebraic expression.

Simplify: 7n² – 9n² + 3n²

Find the sum of: a² + b² + 2ab, 2b² + c² + 2bc and 4c² -a² + 2ac

Subtract the second expression from the first:

2a + b, a + b

Simplify: p + q – (p – q) + (2p – 3q)

Simplify: (p – 2q) – (3q – r)

Factorisation of – 3a² + 3ab + 3ac is 3a(– a – b – c).

Write the greatest common factor in the following terms.

3x³y²z, – 6xy³z², 12x²yz³

The terms of expression 4x² – 3xy are ______.
