Question

( p x^{4}+9 x^{3}+r x^{2}+8 x+z=left|begin{array}{ccc}n^{2}+3 x & x-1 & n+3 x+1 & 2 cdot x & x-3 x-3 & x+4 & 3 xend{array}right| )
for ( t, ) but ( n=0 )
( Rightarrow quad t+0+0+0+t=10-1 quad 3 )
( 1-3 quad 4 quad 0 )
( begin{aligned} Rightarrow quad L=& 1 &=1 quad=30-9 & Rightarrow t=270 mathrm{stus} end{aligned} )

# If px*+qx + 1x² + sx + = 1 x² + 3x x+1 x-3 2 X-1 -x X+4 X+3 X-3 3x then t is equal to - (A) 33 (B)0 (C) 21 (D) none
