Answer» Correct Answer - Option 3 : x = y or the relationship cannot be established. I. 4x2 – 72x + 224 = 0 ⇒ 4x2 – 56x – 16x + 224 = 0 ⇒ 4x(x – 14) – 16(x – 14) = 0 ⇒ (x – 14)(4x – 16) = 0 ⇒ x = 14 or 4 II. y2 – 19y + 60 = 0 ⇒ y2 – 15y – 4y + 60 = 0 ⇒ y(y – 15) – 4(y – 15) = 0 ⇒ (y – 15)(y – 4) = 0 ⇒ y = 15 or 4 Comparison between x and y (via Tabulation):
∴ x = y or the relationship cannot be established. |
