Question

It is given that P(x)=ux^(3)+5x^(2)-7x+v is divisible by x^(2)+x-2.
(a) Find the values of u and v.
[u=4, v=-2]
(b) Solve the equation P(x)=0.

Answer 1

hey use dividend theorem

Answer 2

?

Answer 3

dividend = divisor * quotient + remainder

Answer 4

here remainder is zero

Answer 5

(4x^(3)+5x^(2)-7x-2) / (x^(2)+x-2) ??

Answer 6

hey will catch you after dinner if no one answers i will be availible in 20 min approx.. just gimme a reminder

Answer 7

ok...

Answer 8

@Meepi ....do you have any idea?

Answer 9

Since it is divisble by x^2 + x - 2, roots of that are also roots of P(x)

Answer 10

Do you understand or want me to explain? :)
