Exercise 11 (B) | Q 3.1

Constant is only 8 other is variable 12z ÷ 5x + 4

Group the like term together: ab, – a²b, – 3ab, 5a²b and – 8a²b

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

Add : 18pq – 15pq and 3pq

Simplify: -5ax² + 7ax² – 12ax²

Subtract the second expression from the first:

−2b + 2c, b + 3c

Simplify: 6a – (- 5a – 8b) + (3a + b)

Simplify: `2"a" +(6 - bar("a" - "b"))`

Simplify: {9 – (4p – 6q)} – {3q – (5p – 10)}

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