1.	find the set of values of 'a' if points (1,2)and (3,4) to the same side of the straight line 3x-5y+a=0
Answer» Step-by-step explanation: PUTTING (1,2) and (3,4) should GIVE a result with the same SIGN ⇒ Product of them would be positive ⇒(3−10+a)(9−20+a)≥0 ⇒(a−7)(a−11)≥0 a∈(−∞,7]∪[11,∞)

Answer»

Step-by-step explanation:

PUTTING (1,2) and (3,4) should GIVE a result with the same SIGN ⇒ Product of them would be positive

⇒(3−10+a)(9−20+a)≥0

⇒(a−7)(a−11)≥0

a∈(−∞,7]∪[11,∞)
