Solve x^2 - x - 12 < 0.

x = -4, x = -3

x = -4, x = 3

x = 4, x = 3

x = 4, x = 3

Graph x^2 + 9x + 13 > -7 .

Solve the inequality x² > 4(8 − x).

x<-8 and x>4

x<8 and x>-4

x<-4 and x>8

x<-8 and x>0

One of the roots of 2x^2 – 13x + 20 = 0 is 4. What is the other root?

9/2

-4

-5/2

5/2

Solve x^2 + 9x + 13 < -7.

x = -4, x = -5

x = 4, x = -5

x = -4, x = 5

x = 4, x = 5
