Solution:
Given Expression is ( √6 - 4 )².
Step : Break down into the form of ( a - b ) ²
Step : Arrange it , in the form of Quadratic Polynomial / Expression .
Step : Spilt it into two parts :
___________________________________
( √6 - 4 )²
☞ ( √6 - 4)(√6-4)
☞ √6(√6 - 4) - 4(√6-4)
☞ 6 - 4√6 - 4√6 + 16
☞ 6 - 8√6 + 16
☞ 22 - 8√6
Therefore, Answer is 22 - 8√6
