Find the vertex and intercepts for each quadratic function and sketch its graph.

# 49. y = x^2 - 4x - 12

# 50. y = x^2 + 2x - 24

# 53. Y = - x^2 + 2x + 3

# 54. y = - x^2 - 3x - 2

Use the discriminate to determine whether each quadratic polynomial can be factored, then factor the ones that are not prime.

# 59. 8x^2 - 10x - 3

Solve each inequality. State the solution set using interval notation and graph it.

# 84. a^2 + 2a < 15

# 86. x - x^2 < 0

# 89. x -- 2
----------- > 2
x + 3
