Full year review Algebra 2 (Unit 1 - 6)

Write the equation in vertex form:
y = -2x²+16x+4

• y=-2(x-4)²+4
• y =-2(x+4)²+36
• y=-2(x+4)²+4
• y =-2(x-4)²+36

Solve:           (x-4)²-18 = 0

• x = 4 + 3√2
• x = 8.24, -.24
• x = 4 ± 3√2
• x = 4 ± √18

The quadratic whose roots are -3 and 4.

• x²+x-12
• x²-x + 12
• x²+x+12
• x²-x-12

What is the value: √-9 ⋅ √-16

• -12
• 12i²
• 12i
• -12i

 Simplify:
 $\frac{2+3i}{5+2i}$ 

•  $\frac{11+16i}{29}$  
  

•  $\frac{16+11i}{29}$  

•  $\frac{16}{29}$  

•  $\frac{4+11i}{29}$  

What is the vertex:
y = 2(x-3)²+18

• (-3,-18)
• (3,-18)
• (-3,18)
• (3,18)
