Question

If (x+5)² = 100, the possible value of 'x' is

Answer 1

(x+5)^2=100

or, x+5=sq.root 100

or, x+5=10

or, x=5

Answer 2

Answer:x=-15 or 5

Step-by-step explanation:

x2+10x+25=100

x2+10x-75=0

p=_75(15*-5)

s=10(15+-5)

x2+15x+-5x-75

x(x+15)-5(x+15)

(x+15)(x-5)

x+15=0              x-5=0

x=-15                  x=5
