Algebra II Ch 6

Quadratic Expression- ax^2_bx+c is the general quadratic expressionin the variable x. Quadratic Equation- ax^2+bx+c=0 is the general quadratic equation in the variable x. Quadratic Function- f:x --->ax^2+bx+c is the general quadratic function. Postulate-- all postualtes for real nmbers excepts those for inequalities also hold for the set of complex numbers.
Standard form of the quadratic- ax^2+bx+c irrationalyly bad time.
Binomial Square Theorem- For all real numbers x and y, (x+y)^2=x^2+2xy+y^2 and (x-y)^2=x^2-2xy+y^2.
Absolute Value- The operation or function defined by: the distance from x to 0 on a number line.
Theorem-- the graph of the equation y=ax^2+bx+c is a parabola congruent to the graph of y=sx^2
Perfect Square Trinomial- (X+h(=x^2+2hx+h^2
Definition-- when k>0, the two solutions to x^2 are denoted *-k and -*-k Definition i=*-1 Theorem-- if k>0, *-k and ik
