#1**+2 **

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.
