y2– 4 = 0
In following question, two equations are given, you have to solve them and choose the correct option: x2– 3x – 4 = 0, y2– 4 = 0
ক)
x = y or relation cannot be determinedখ)
x > yগ)
x < yঘ)
x ≥ yঙ)
x ≤ yExplanation
x 2 - 4x + x – 4 = 0 ⇒ x (x-4) + 1(x-4) = 0 ⇒ (x+1) (x-4) = 0 x = -1 , x = 4 y 2 – 4 = 0 y 2 = 4 y = +2, -2 (x=4) > y= (+2,-2) ---- (i) x=(-1) < y = 2 ---- (ii) Hence, relation cannot be determined.Related questions
