Answer:

This gueshion is 8 clas

Answer 2

Answer:

2) [a/2 -b/3 +1]^2

=> a^2/4 - b^2/9 +1 +2[-ab/6 - b/3 + a/2]

=> a^2/4 - b^2/9 +1 -ab/3 -2b/3 + a

3) 7+3√5/7-3√5

=> [7+3√5 / 7-3√5] [7+3√5 / 7+3√5] {Rationalizing denominator}

=> [7+3√5]^2 / 49-45                          [{7+3√5}{7-3√5}= 49 - 9(5) = 49-45]

=> 49 + 45 + 2(7)(3√5) / 4

=> 94+42√5 / 4

=> 26+21√5 / 2

Hope it helps
