Simplify Binomials

Expand and simplify the following:

(a + 3)(a + 7)

• Expanded = a^2 + 7a + 3a + 23

  
  Simplified = a^2 + 10a + 23

• Expanded = a^2 + 7a + 3a + 21
  
  Simplified = a^2 + 10a + 21
  

• Expanded = a^2 + 7a + 3a + 21
  
  Simplified = a^a + 21a + 21

• Expanded = a^2 + 7a + 3a + 10
  
  Simplified = a^2 + 10a + 10
