Which equation is equivalent to x^2 - 16x + 49 = 0?

Subtract 49 by its negative so now

x^2-16x=-49

then move - 16 so

x^2=-49+16x

then add - 49 and 16 so then you get

X^2+your answer)

then find the square root because this was in exponential form so find the square root of x^2 and of your answer so

X = Your answer
