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

EG $\displaystyle x^2+3x+2>0$ $\displaystyle (x+2)(x+1)>0$ This means that the only way the statement is true is if x is anything but in $\displaystyle [-2,-1]$.

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