What equation results from completing the square and then factoring? x^+22x=31

(a)

(b)

Step-by-step explanation:

We are given

Since, we have to complete square

so, we can use formula

so, we can add both sides by 1^2

now, we can use formula

and we get

so, equation after completing square is

now, we can solve for x

we can move all terms on left side

now, we can factor it
