1 answer:

6 0

Hi dear,

log(x+3)-log10+logx+1=0

log(x+3)-1+logx+1=0

log(x+3)+logx=0

logx(x+3)=0

x(x+3)=10^0

x^2+3x-1=0

solve this equation that answers are:

X1= [ (13)^(1/2) - 3]/2

X1= [ (13)^(1/2) + 3]/2

finlep [7]

Answer:

=x^2 +4x+11

Step-by-step explanation:

Replace x with x+2

f(x+2) = (x+2)^2 + 7

= (x+2)(x+2) +7

FOIL
