Algebra 2

 Graph the quadratic equation. Vertex: (-3, 4) Axis of symmetry: x = -3

 Simplify radical expressions  Rationalize the denominator  Solve quadratic equations

 Product Property:  Quotient Property:

1.No fractions in square roots 2.No perfect squares in the radical 3.No radicals in the denominator Did you know…? That it is against the law in 32 states (including Illinois) to leave a radical in the denominator of a fraction.

Steps: 1.Use a “factor tree” to factor completely 2.Circle pairs of the same number (they go out) 3.Any other factors not part of a pair stay in
