Question

sol: ( sqrt{45} x^{2}+11 sqrt{5} x-4 sqrt{5}=0 )
Bividing with ( sqrt{5} rightarrow ) ( sqrt{9} x^{2}+11 x-4=0 )
( 3 x^{2}+11 x-4=0 )
( 3 x^{2}+12 x-x-4=0 )
( 3 x(x+4)-1(x+4)=0 )
( (3 x-1)(x+4)=0 )
( Rightarrow quad x=frac{1}{3},-4 )
( Rightarrow quad ) facters are: ( (3 x-1)+(x+4) )

# ai factorize each of the following Sun & Jusx?FLIVEX -405
