Answer with Step-by-step explanation:

We are given a expression:


11x-2-3(1-7x)^2+(x+1)

We have to determine the first step in the solution of the above expression.

First step will be to solve the term
(1-7x)^2

We will firstly square the term 1-7x


11x-2-3(1-7x)^2+(x+1)\\\\=11x-2-3(1+49x^2-14x)+(x+1)\\\\=11x-2-3-147x^2+42x+x+1\\\\=-147x^2+54x-4

Hence, First step is:

solve the term
(1-7x)^2
