Answer 2

Answer:

(c) 12√2

Step-by-step explanation:

2x² + ax + 32 = 0

roots : p & q

condition : p = 2q

now....

p + q = - (a/2) ; p•q = 32/2

means....

2q + q = -a/2 ; 2q•q = 16

3q = -a/2 ; 2q² = 16

(3q)² = (-a/2)² ; q² = 16/2

9q² = a²/4 ; q² = 8

hence....

9q²/q² = a²/4(8)

9 = a²/32

a² = 9•32 = 288

a = √288

a = 12√2

therefore...

a = 12√2
