Question

what is the term for 3x linier expansions​

Answer 1

Step-by-step explanation:

first we note that coefficient of cubical expansion =3x co-efficient of linear expansion

coefficient of superficial expansion =2 x coefficient of linear expansion

now it is given that coefficient of cubical expansion of Q is three times the coefficient of superficial expansion of P .

so, 3 x coefficient of linear expansion of Q=3

x 2 x coefficient of linear expansion of P
