Question

How do you solve the inequality, x squared + 3x - 4 is less than or equal to 0 ?

Answer 1

\[x^{2} +3x -4 \le 0\]

forget the inequality and solve like this:

\[x^{2} +3x -4 = 0\]

When you get the values for X then X must be less than or equal to those values

Answer 2

well actually i was wrong. X must be inside those values so let's say the answer is -4 and 1
then
\[-4 \le x \le 1\]

Answer 3

thanks :)
