Answer #2

SOLUTION :

A.

x^2 + 5x = 0

Converting to completed square form :

=> (x + 5/2)^ - (5/2)^2 = 0

=> (x + 5/2)^2 = 25/4

So , x^2 + 5x is equivalent to :

( x + 5/2)^2 = (5/2)^2 (ANSWER).

B.

(x + 5/2)^2 = (5/2)^2

Taking square root on both sides :

=> x + 5/2 = +/- 5/2

=> x = 0 , - 5 (ANSWER)
