me assume that stuf shood be
x^2 +5x -2 < 0
step 1...find x^2 +5x-2=0
quadratik equashin giv (x-0.3722813)*(x+5.3722813)=0
or y=0 at x=-5.3722813 & at x=0.3722813
bekauz av the x^2 term, we no y become very bit + number wen x get bit & wen x get negativ big
thus, y < 0 wen x tween -.5.3722813 & 0.3722813
