Answer 1

Answer:

(p +5)²  = 26

Step-by-step explanation:

p²+10p = 1

try to arrange them like a²+2ab+b² ;

     

here,

a² = p²  →      ∴a=p

and,

2ab = 10p

⇒2ab = 10a    [∵a=p]

∴ b=5            [dividing both sides by 2a]

∴b²=5²

hence,

⇒ p² + 2 .p.5 + 5² = 1+5²   [add  5² on both sides ]

⇒ (p +5)²  =1+25

∴  (p +5)²  = 26
