In following question, two equations are given, you have to solve them and chose the correct option:
x2+ 11x + 30 = 0,
y2+ 7y + 12 = 0
In following question, two equations are given, you have to solve them and chose the correct option: x2+ 11x + 30 = 0, y2+ 7y + 12 = 0

x ≤ yExplanation
x 2 + 11x + 30 = 0 ⇒ x 2 + 6x + 5x + 30 = 0 ⇒ x(x+6) + 5(x+6) = 0 ⇒ (x+5) (x+6)=0 X = -5, -6 y 2 +7y + 12 = 0 ⇒ y 2 + 4y + 3y + 12 = 0 ⇒ y (y+4) + 3(y+4) = 0 ⇒ (y+3) (y+4) = 0 Y =-3, -4 ∴ x < yRelated questions
