Divide -4, the coefficient of the x term, by 2 to get -2. Then add the square of -2 to both sides of the equation. This step makes the left hand side of the equation a perfect square. Factor x^ {2} …

Solve for x in math means finding the value of x that would make the equation true. To get a variable by itself a combination of algebraic techniques is requiered.

Just like numbers have factors (2×3=6), expressions have factors ((x+2)(x+3)=x^2+5x+6). Factoring is the process...
