1)Find the exact solutions to 3x^2=5x-1 using the quadratic formula.

answer=5 plus or minus the square root of 37 over 6

2)Use the discriminant to determine the number and type of roots for the equation 2x^2-7x+9=0

answer=2 complex

3)Identify the vertex,axis of symmetry,and direction of opening for y=1/2(x-8)^2+2

answer=(8,2);x=-8;up

4)Which quadratic function has its vertex at(-2,7)and opens down?

answer=y=(x-2)^2+7

5)Write y=x^2+4x-1 in vertex form

answer=y=(x-2)^2+5
