Question

anybody can solve problem this problem please and Happy Republic Day

Answer 1

x²+6x+9=0
= x²+(3+3)x+9=0
x²+3x+3x+9=0
x(x+3)+3(x+3)=0
(x+3)(x+3)=0
thus
[x+3)²=0
x+3=0
so x= -3


hence prove...

Answer 2

Answer:

Step-by-step explanation: x=(-3)

P(x)= x^2 +6x+9

=(-3)^2 + 6×(-3) +9

= 9+(-18)+9

=9-18+9

=(9+9)-18

=18-18

=0

Hence proved
