Question

if (y-5y) (x^2+2x+4) <2,x belongs toR then number of integer in the range of y​

Answer 1

Answer:

Hey mate ,

here is your answer

We can write the given inequality as y2−5y+2<2xx2+x+1.

Now we will calculate range of

z=2xx2+x+1⇒zx2+zx+z=2x

So

zx2+x(z−2)+z=0,

Now if given equation has real roots, Then Discriminant≥0
