Question

Verify whether (x + 1), (x – 2) and (x + 3) are the factors of the polynomial x3 + 2x2

– 5x – 6 without actual

division.​

Answer 1

Answer:

X+1 and X+3 a factor but

X+2 leaves 4 as a remainder

Step-by-step explanation:

it is simple by remainder theorem take (X+1),(X+2)and (X+3) =0

which gives -1,-2 and -3 respectively now put -1,-2 and -3 in the space of X solve three of them and the answer will come written above
