Key Strategy in Solving Quadratic Equations using the Square Root Method.
The name Quadratic comes from quad meaning square because the variable gets squared like x 2. Quadratic kwo-drat ik Relating to a mathematical expression containing a term of the second degree such as x 2 2 A quadratic equation is an equation having the general form ax 2 bx c 0 where a b and c are constants The quadratic formula is x -b b 2 - 4ac2a. The general approach is to collect all x2 terms on one side of the equation while keeping the constants to the opposite side. A method usually of solving quadratic equations by which a quadratic expression as x 2 4x 3 is written as the sum or difference of a perfect square and a constant x 2 4x 4 3 4 x 2 2 1 by addition and subtraction of appropriate constant terms.
