Answer 2

Answer:

Step-by-step explanation:

1. (1/a+1/b)=a+b/ab

given 2x^2+3x+5

sum of roots a+b=-3/2

product of roots=ab=5/2

now

(3/2)/(5/2)=3/5

2. a+1/a=-11/6

a*1/a=1=-(k-2)/6

k-2/6=-1

k-2=-6

k=-4

3. given 3x^2+ax-14 and 2x^3+bx^2+x-2

p(2)=0 in both cases

3(2^2)+2a-14=0

12-14+2a=0

2a=2

a=1

2(2^3)+b(2^2)+2-2=0

2(8)+4b=0

4b=-16

b=-4

a-2b=1+8=9

4. a+b=1/4

ab=-1

given k(x^2-(b/a)x+(c/a))

k(x^2-(1/4)x-1)

=4x^2-x-4 is the required polynomial
