• seriously... don't get this one wrong. thanks.

Factor the trinomial : x² -11x + 30

• (x+5)(x+6)

• (x-10)(x-3)

• (x-5)(x-6)

• (x+10)(x+3)

Factoring the Trinomial: x² + 12x + 27

• (x-9)(x-3)

• (x+5)(x+7)

• (x+9)(x+3)

• (x+9)(x-3)

Find the coordinates of the vertex of the graph of    y = x² – 8x + 10. Identify the vertex as a maximum   or a minimum

• (4, –6); minimum        
• (–4, 58); maximum 
• (4, 6); maximum
• (–4, 26); minimum

**round to the nearest tenth if necessary
Solve x² + 4x = 20 by completing the square

• x = 2.90 and 6.90
• x = -2.90 and -6.90
• x = -2.90 and 6.90
• x= 2.90 and -6.90

What is the standard form of a quadratic function?

• y = mx + b

What is the vertex form of a quadratic function?

• y = mx + b
• ax² + bx +c =0
• y = a(x-h)² + k

Mult (2x + 3)(3x + 4)
