Standard Form and Vertex Form

• y = 9x² - 15x + 21

• y = -3x² - 75x - 4

• y = 9x² + 90x + 221

• y = -3x² - 30x - 79

• y = -5x² - 20x - 30

• y = -5x² - 4x - 10

• y = 25x² + 100x + 90

• y = 25x² - 10x - 30

$y=\left(x+\frac{1}{2}\right)^2-2$

Convert the equation from vertex form to standard form.

Use the ^ (shift 6) to show the power (no spaces)
