Thread: Inequality help needed!

I've tried and tried but I can't solve these two inequalities
Would you please help me, I'd really appreciate it

X^2 + X - 2 < 0

and:

5X - 2 > 0

Hi BobbyJean

Are there 2 separate questions or just one question consists of 2 inequalities?

Anyway, can you fatorise X^2 + X - 2, then find the critical values, then find the range where X^2 + X - 2 < 0

1. factor

2. solve like an equation

Do you know how to factor?

EG



This means that the only way the statement is true is if x is anything but in

These are two separate questions and I can't solve them

Hi BobbyJean

Well, you've been given hints. First step, can you factorise X^2 + X - 2 ?

No I can't
