How do you factor by completing the square
WebCompleting the square is a technique for rewriting quadratics in the form (x+a)^2+b (x +a)2 +b. For example, x^2+2x+3 x2 +2x +3 can be rewritten as (x+1)^2+2 (x +1)2 +2. The two expressions are totally equivalent, but the second one is nicer to work with in some β¦ WebTo factor the equation, you need to first follow this equation: x^ 2 + 2ax + a^2. In x^2 +5x = 3/4, The a^2 is missing. To figure out the a, you need to take the 5 and divide it by 2 (because 2ax), which becomes 5/2. a=5/2. Then you need to square it, (because a^2) which β¦
