Question

On real axis if a=1-5 and b=3-9, then A-B is

Answer 1

Step-by-step explanation:

9(25a2+b2)+25(c2−3ac)=15b(3a+c)

225a2+9b2+25c2−75ac=45ab+15bc

225a2+9b2+25c2−75ac−45ab−15bc=0

(15a)2+(2b)2+(5c)2−(15a)(5c)−(15a)(3b)−(3b)(5c)=0

(15a)2+(2b)2+(5c)2=(15a)(5c)+(15a)(3b)+(3b)(5c)

15a=3b=5c=k

b=5a and c=3a

Hence, a=15k, b=3k and c=5k

∴b−a=154k

and
