Let the no. to be added be k
Therefore,
the factors of the polynomial are:
x²+2x-3------> x² + 3x-x -3------> (x+3)(x-1)
Using x=1,
1⁴ + 2(1)³ -2(1)² +1-1+k=0
1+2-2+1-1+k=0
k=-1
Therefore,
the factors of the polynomial are:
x²+2x-3------> x² + 3x-x -3------> (x+3)(x-1)
Using x=1,
1⁴ + 2(1)³ -2(1)² +1-1+k=0
1+2-2+1-1+k=0
k=-1
