Question

solution of (x-2)(x+5)<=0 ?

Answer 1

zeros are at \(-5\) and \(2\) and since \(y=(x-2)(x+5)\) is a parabola that faces up, it is negative between the zeros i.e. if \(-5\leq x\leq 2\)

Answer 2

right, I forgot the graph. thanks!

Answer 3

Yep, a graph helps you to see where the graph is below the x-axis.
