Exercise 11 (B) | Q 6.2

For the following monomials, write its degree: xy²z

Group the like term together: 9x², xy, – 3x², x² and – 2xy

Fill in the blank:

The addition of 5, 7xy, 6 and 3xy = _____

Subtract the second expression from the first:

3a² - 8ab - 2b² , 3a² - 4ab + 6b²

Simplify: 5 x (2x + 3y) – 2x (x – 9y)

Common factor of 12a²b² + 4ab² – 32 is 4.

Factorise the following expression.

4xy² – 10x²y + 16x²y² + 2xy

Identify the numerical coefficient of term (other than constant) in the following expression:

2(l + b)

Number of terms in the expression 3x²y – 2y²z – z²x + 5 is ______.

Coefficient of x in –9xy²z is ______.
