Question

verify that 2,1,1 are zeroes of polynomial x3 - 4x2 +5x - 2.also verify the relationship between the zeroes and coefficient .

(please fully solve the answer and then post it) ​

Answer 1

Step-by-step explanation:

P(x)=x3-4x2+5x-2

fill x 2;1;1 in each case if in all case the reminder seems to be come out to be zero then they are the zeros of polynomial P of x.

the apply the following equations to verify the relationship between the coefficients of zero.

1- 1st 0 + 2nd zero + 3rd zero=-b/a (cofficents)

2-1st 0×2nd zero× 3rd zero =-d/a

3- 1st × 2nd +2nd ×3rd+3rd ×1st=c/a

hope it helps...
