Y= (x-1) 2 +2 Y = (x-5) 2 -3 Put into standard form Then find the Axis of Symmetry Vertex Y intercept
Factoring Quadratics
Distributive Factoring Look for a common factor in each term Surround the expression with ( ) Write the common factor in front Divide each term by the common factor
example 3x 2 +6x + 18 (3x 2 +6x + 18) 3(x 2 +2x + 6)
Factoring ax 2 +bx+c Find 2 factors with the product of ac and the sum of b Rewrite bx as the sum of the 2 factors times x Find common factors Rewrite using the distributive property
Example a = 1 x 2 +7x+6 ac = 6b=7 Factors of 62,31,6 Sum of factors57 x 2 + x + 6x + 6 (x 2 + x) + (6x + 6) x(x + 1) + 6(x + 1) (x + 6) (x + 1)
