Question

Subtract 3m³ + 4 from 6m³ + 4m² + 7m – 3 in stepwise method.

Answer 1

Let us solve this in stepwise. 

Step 1: 6m³ + 4m² + 7m – 3 – (3m³ + 4) 

Step 2: 6m³ + 4m² + 7m – 3 – 3m³ – 4 

Step 3: 6m³ – 3m³ + 4m² + 7m – 3 – 4 (rearranging like terms) 

Step 4: (6 – 3)m³ + 4m² + 7m – 7 (distributive law) 

Thus, the required answer = 3m³ + 4m² + 7m – 7
