factorise :a³-a²b= _____​

Answer 1

Question:

Factorise :a³-a²b

Answer:

• First we will take the a as common
• Then check which one is the smaller : a² or a³
• a² is smaller so take that out side the bracket
• = a²(a³ - b)
• Now, subtract the inner common value with the outer value of the bracket
• a³-a² = a
• And replace the value inside the bracket with it
• a²(a - b) is the answer
