b) -b/a>0

c) c/a<0

d) -b/a<0 ​

Answer 1

$\small\bigstar\red{\boxed{AnsWer}} \bigstar$

here is the full explanation.....

CONDITIONS FOR BOTH ROOTS TO BE REAL & NEGATIVE: (1) If D > 0, there will be REAL roots. (2) If D>0, & all terms of the quadratic equation are positive then both roots will be NEGATIVE. (3) If D>0, & any one of the terms is negative.
