Exercise 11 (B) | Q 2.2

Identify term which contain y² and give the coefficient of y².

8 - xy²

Constant is only 8 other is variable 12 – 5 z – 4

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

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

Simplify: `"b"("2b" - 1/"b") - "2b"("b" - 1/"b")`

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

Simplify: `"x" - ("3y" - bar"4x - 3x" + 2z - bar"5y - 7x")`

The factors of a² – 2ab + b² are (a + b) and (a + b).

Factorise the following expression.

– xy – ay

Identify term which contain x and give the coefficient of x.

1 + x + xy
