QUADRATIC EQUATIONS A QUADRATIC equation is always written in the form of: axbxc20+ + = where a 0 The form axbxc20+ + = is called the standard form of a QUADRATIC equation. Examples: xx2560 + = This is a QUADRATIC equation written in standard form. 442 =+xx This is a QUADRATIC equation that is not written in standard form but can be once we set the equation to: xx2440+ + =. xx2= This too can be a QUADRATIC equation once it is set to 0. xx20 = (standard form with c=0). Solving QUADRATIC EQUATIONS by Square Root Property Whenax=2, where a is a real number, then your ax = Examples: 092= x 23 28y+= 092= x 23 3 28 3y+ = 92=x 225y= 9 =x 25y= 3 =x 5y= Solving QUADRATIC EQUATIONS by Factoring It can also be solved by factoring the equation.
QUADRATIC EQUATIONS . A quadratic equation is always written in the form of: . 2 . ax +bx +c =0 where . a ≠0. The form . ax. 2 +bx +c =0 is called the . standard form. of a quadratic equation.
