What is the standard form of quadratic inequality?

• ax² + bx + c < 0

• ax² + bx < -c

• ax² + bx < c

• ax² + c < bx

Solve x² - x - 12 < 0.

• x = 4, x = -3

• x = 4, x = 3

• x = -4, x = 3

• x = -4, x = -3

Solve x² + 9x + 13 < -7.

• x = -4, x = -5

• x = 4, x = 5

• x = -4, x = 5

• x = 4, x = -5
