Question

( f(y)=y^{3}-2 y^{2}+y+4 )
By Hur and truil purtey ( y=-1 )
( P(-1)=(-1)^{3}-2(-1)-1+ )
( y=-1 quad u )
( 7^{p(y} )
( y_{1}+sum y^{3}-2 y^{2}+y+1+left(y^{2}-3 yright. )
( frac{-y^{3}+y^{2}}{-3 y^{2}+y+4} )
( -3 y^{2}-83 y )
( frac{(t)}{4 y+r} )
( y^{2}-3 y+4=y^{2}-4 y+7+1 )
( y=frac{+3+sqrt{9-4 x}}{2}=frac{pm 3 pm sqrt{-7}}{2} )
( frac{3 pm 7 i}{2} )
( y=1, frac{317 i}{2} mid ) Teacher signature
