Question

If p(x)=x⁴-2x²+3x²-ax+3a-7 is divided by (x+1), then the remainder is 19. Find the value of a​

Answer 1

Step-by-step explanation:

May be I think this is answer

Answer 2

Answer:

p(x)=x⁴-2x^3+3x²-ax+3a-7 is divided by (x+1)

then the remainder is p(-1),[since,(x+1)=0,Or, x=(-1)]

now,the remainder is 19.

so, p(-1)=19

Or, (-1)⁴-2(-1)^3+4(-1)²-a(-1)+3a-7=19

Or, 1+2+4+a+3a=19+7

Or, 4a=26-7=19

Or, a=19/4

[I think you mistakenly write 2x^2 in the equation.if not then please comment.i will solve it again]
