  • 7a²b+5ab²-4ab²-3ab²+2a²b²

Combine like terms

  • 5ab²-4ab²-3ab²+7a²b+2a²b²
  • (5-4-3)ab²+7a²b+2a²b²
  • -2ab²+7a²b+2a²b²

Two factorisation ways

  • 7a²b-2ab²(1+a)

Or

  • ab(7a-2b+2ab)

abruzzese [7]

Nuetrik [128]

The handshake is an illustration of combination, and the values of n and r are 21 and 2, respectively

<h3>How to determine the values of n and r?</h3>

The number of students in the class is 21.

This represents the value of n

i.e. n = 21

Each student shakes hand with another student (i.e. 2 students per handshake)

This represents the value of r

i.e. r = 2

Hence, the values of n and r are 21 and 2, respectively
