Solution

Given expression: 2x2 + 7x – 3xz

Step-wise calculation:

In this expression, note that each term contains x as a factor:

  • First term: 2x2 = x × 2x
  • Second term: 7x = x × 7
  • Third term: –3xz = x × (–3z)

Therefore, we can factor out x from all terms:

2x2 + 7x – 3xz = x(2x + 7 – 3z)
