Answer with Step-by-step explanation:
We are given a expression:
[tex]11x-2-3(1-7x)^2+(x+1)[/tex]
We have to determine the first step in the solution of the above expression.
First step will be to solve the term [tex](1-7x)^2[/tex]
We will firstly square the term 1-7x
[tex]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[/tex]
Hence, First step is:
solve the term [tex](1-7x)^2[/tex]
