Question 692459
There is a mix-up. The multiple choice answers make no sense.
They seem related to a different problem.
They seem to be the answers to problem # 692455, posted earlier, asking which equation had {{{-2}}} and {{{1/5}}} as solutions
Soemeone copied and pasted the wrong answer choices.
If it was not you, it reminds me of the online AP Physics course my youngest son was taking years ago. It was so badly put together that I still hate the course provider.
 
To solve {{{9x^2-12x+4=49}}}, I would first
notice that {{{9x^2-12x+4=(3x-2)^2}}} is a perfect square of a binomial,
and then I would re-write the equation as
{{{(3x-2)^2=49}}}
