Question

i don't know the steps to solving this equation :3

Solve the following inequalities, and graph your solution on a number line:

a. 6x^2+29x >-30
b. x^2+ 3x + 4 > 0

Answer 1

Hint: Use quadratic formula

Answer 2

so you just plug in the numbers and you're done?

Answer 3

a.6x^2+29x >-30
<=>6x^2+29x+30 >0
<=>x=-3/2 or x=-10/3
if x <-3/2, the other x must be < -10/3 for the ans to be 0
if x > -3/2, the other x must be > -10/3 for the ans to be 0
=>x>-3/2
=> x<-10/3
just do the same thing with the second one, then you'll have the solutions

Answer 4

im still confused...

Answer 5

which part?
