x2+nx+15<−89−3x2
so i first brought everything to the left side to get 4x2+nx+104<0
then i divided by 4 to getx2+n4x+26<0
for x to have no real solutions the discriminant must be negative
so n216−4(26) must be negative. the less than sign is useless since smaller right hand values make c greater
the greatest value of n that works is 40
but we also can have negatives, least of which is -40
so -40 to 40 is 81 numbers
