Solve using the quadratic formula.
2x² - 9x - 35 = 0

• x = 7/2, x = -6

• x = -5/2, x =5

• x = -3/7, x =6

• x = -5/2, x = 7

Factor completely.

2n² + 13n + 15

• (5n - 9)(n - 3)

• (3n + 7)(n + 4)

• (2n + 3)(n + 5)

• Not factorable

(2x³ - 5x² + 3x + 7) ÷ (x - 2)

• 2x³ - x² + x + 9

• 2x² - x + 1

• 2x² - x + 1 + 9/x-2

• 2x² - 9x - 15 - 23/x-2

(5x+2)(x²-3x+6)

• 5x³ - 17x² +24x +12

• 5x³ + 17x² - 24x +12

• 5x³ - 13x² + 24x +12

• 5x³ +13x² - 24x - 12

• 30x²-38x-16

• 30x²+38x-16

• 35x²+38x-16

• 30x²+38x+16

Solve the equation by factoring:
x² -5x = 24

• x = ±√5

• x = -8 and 3

• x = 8 and -3

• No Real Solution

Convert the equation from vertex form to standard form.

• y = 9x² - 15x + 21

• y = -3x² - 75x - 4

• y = 9x² + 90x + 221

• y = -3x² - 30x - 79

Write the following quadratic equation in vertex form... y = x² - 12x + 25

• y = (x - 6)² + 13

• y = (x - 6)² - 11

• y = (x - 6)² + 11

• y = x + 6)² - 13
