Answer 1

Step-by-step explanation:

16. a + b =p (x+1)

and ab = -c

now

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

= ab +(a+b)+1

putting values we get

(a+1)(b+1)= -c+p(x+1)+1

so answer is non of these

17. a+b=-3/4

ab=7/4

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

putting values

we get

1/a+1/b= -3/7

18.

let the roots be a and a-1

now alpha +beta = 2a

2a=b

also alpha×beta = a^2-a =c

b^-4c = 4a^2-4a^2+4a

=4a

now find the value of a
