Question

The polynomial p(x) = x4 -2x3 + 3x2 -ax+3a-7 when divided by x+1 leaves the remainder 19. Find the values of a

Answer 1

Answer:

5

Step-by-step explanation:

X4-2X3+3X2-AX+3A-7----------------(1)

LET X+1=0

X=-1

PUTTING THE VALUE OF X IN EQ 1

(-1)4-2(-1)3+3×(-1)2-A×-1+3A-7=19

1+2+3+A+3A-7=19

4A-+6-7=19

4A-1=19

4A=19+1

4A=20

A=20×4

A=5
