Hello!
Ignore the negative and solve the square root which is 13.
Add the negative with 13 you get -13

But for this question just solve it directly.
Have a great day!
Put the terms in order of decreasing degree, all on the left. When convenient, it is nice to have mutually prime integer coefficients with the leading one positive.
a) x² -2x +1 = 0
b) x² +15 = 0
c) 4x² -12 = 0
or, better, divide out the common factor of 4.
x² -3 = 0
d) 3x² -x -5 = 0
