Solution

The correct option is C p $\leq$ q
$(I) 2 p^{2} + 20 p + 50 = 0 \Rightarrow p^{2} + 10 p + 25 = 0 \Rightarrow (p + 5)^{2} = 0 \Rightarrow p + 5 = 0 \Rightarrow p = - 5 (I I) q^{2} = 25 \Rightarrow q = \pm 5 O b v i o u s l y, p \leq q$

$I . 2 p^{2} + 20 p + 50 = 0 I I . q^{2} = 25$

The correct option is C p $\leq$ q
$(I) 2 p^{2} + 20 p + 50 = 0 \Rightarrow p^{2} + 10 p + 25 = 0 \Rightarrow (p + 5)^{2} = 0 \Rightarrow p + 5 = 0 \Rightarrow p = - 5 (I I) q^{2} = 25 \Rightarrow q = \pm 5 O b v i o u s l y, p \leq q$
