Directions (next five questions) : In these questions, two equations numbered I and II have been given. You have to solve both the equations and
I. 2x2+23+63=0
II. 4y2+19y+21=0
2x2+14x+9x+63 = 0
2x(x+7)+9(x+7) = 0
(x+7)(2x+9)=0
x=-7 or -9/2
4y2+12y+7y+21=0
4y(y+3)+7(y+3)=0
(y+3)(4y+7)=0
y=-3 or -7/4 ⇒ y>x
Directions (next five questions) : Refer to the graph and answer the given questions.
