For what values of x is it true that \(x^2 - 5x - 4 \le 10\)? Express your answer in interval notation.
Subtract 10 from both sides of the equation to get
(x-7)(x+2) <= 0
x =7 and -2 for thequation to EQUAL 0 intervals : -inf to -2 -2 to 7 and 7 to +inf
which do you think satisfy the equation?
so is -2 to 7 what I put in? I am on AoPS this stuff is really confusing.
