In the given question, two equations numbered l and II are given. Solve both the equations and mark the appropriate answer.I: x2 + 6x – 247 = 0II: y2 + 27y + 182 = 01.x &gt; y2.x ≤ y3.x = y or the relationship between x and y cannot be established.4.x ≥ y5. x < y

Answer» Correct Answer - Option 3 :

x = y or the relationship between x and y cannot be established.


Calculation:

I: x2 + 6x – 247 = 0

⇒ x2 – 13x + 19x – 247 = 0

⇒ x × (x – 13) + 19× (x – 13) = 0

⇒ (x – 13) × (x + 19) = 0

⇒ x = (-19), 13

II: y2 + 27y + 182 = 0

⇒ y2 +14y + 13y + 182 = 0

⇒ y × (y + 14) + 13 × (y + 14) = 0

⇒ (y + 13) × (y + 14) = 0

⇒ y = -14, -13

Comparison between x and y (via Tabulation):
