For what values of x is it true that \(x^2 - 5x - 4 \le 10\)? Express your answer in interval notation.

#1**+2 **

Subtract 10 from both sides of the equation to get

x^2-5x-14 <=0

(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?
