Hey there, Guest!
I don't get what the "completing the square" part means, but I'll answer your linear equation.
Step 1: Simplify both sides of the equation.
16x+4=3
Step 2: Subtract 4 from both sides.
16x+4−4=3−4
16x=−1
Step 3: Divide both sides by 16.
\(\frac{16x}{16}\)=\(\frac{-1}{16}\)
\(x=\frac{-1}{16}\)
If you missed that, the answer is -1/16.
Hope this helped! :)

Maybe you meant 4^x^2 + 16x =3 ? Divide through by 4
x^2 + 4x = 3/4 take 1/2 of the x coeffecient (which is 4) ....square it and add it to the equation on both sides
x^2 +4x + 4 = 3/4 +4
(x+2)^2 = 4 3/4 now take sqrt of both sides
x+2 = ±√(19/4)
x = -2 ±√(19) /2
Hello! Completing the square is not used for linear equations, it is a method of turning the quadratic $ax^2+bx+c=0$ into the form $a(x+b)^2+c=0$, which is not applicable for linear equations.
