Show Answer

Answer:

Correct Answer: A

Solution:

I. $ 2x^{2}+23x+63=0 $

$ \Rightarrow $ $ 2x^{2}+14x+9x+63=0 $

$ \Rightarrow $ $ 2x(x+7)+9(x+7)=0 $

$ \Rightarrow $ $ (x+7)(2x+9)=0 $

$ \Rightarrow $ $ x=-7, $ $ x=-\frac{9}{2} $ II. $ 4y^{2}+19y+21=0 $

$ \Rightarrow $ $ 4y^{2}+12y+7y+21=0 $

$ \Rightarrow $ $ 4y,(y+3)+7,(y+3)=0 $

$ \Rightarrow $ $ (y+3)(4y+7)=0 $

$ \therefore $ $ y=-,3, $ $ y=-\frac{7}{4} $ Hence, $ y>x $
