Convert
 y = 3(x+1)² - 8 into standard form.

• y=3x² + 6x - 5

• y=3x² - 6x - 5

• y=3x² + 6x + 5

• y=3x² - 6x + 5

Convert the equation from vertex form to standard form.

• y = -5x² - 20x - 30

• y = -5x² - 4x - 10

• y = 25x² + 100x + 90

• y = 25x² - 10x - 30

Convert this equation in vertex form to standard form.

• x² -2x - 2

• x²+x-2

• x²+2

• x²-2x

Convert the equation into standard form:

• y = -5x² - 20x - 30

• y = -5x² - 4x - 10

• y = 25x² + 100x + 90

• y = 25x² - 10x - 30
