Convert from Standard Form to Vertex Form

Convert to vertex form.
y = 3x² +6x - 5

• y=3(x+1)² - 8

• y=3(x-1) ² - 8

• y=3(x+2)² - 8

• y=3(x-2)² - 8

What is the vertex form of the quadratic equation y = x^2 - 4x + 4 after completing the square?

• y = x^2 + 4x + 4

• y = (x - 2)^2

• y = (x - 4)^2

• y = (x + 2)^2

Convert to vertex form.

• y=-(x-5)² + 21

• y=-(x+5)² + 21

• y=-(x+10)² + 21

• y=-(x-10)² + 21

After completing the square in the equation y = x^2 + 6x + 9, what is the resulting perfect square trinomial?

• (x + 3)^2

• (x + 5)^2

• (x + 2)^2

• (x + 4)^2
