Question

what is the resulting equation when the polynomials are multiplied?
choices: (2w^2- 11w + 15 =55)
(2w^2- 11w - 15 =55)
with a solution, please.

Answer 1

Answer:

(a) a,b,c are lengths of sides of an scalene triangle. If equation

x

2

+2(a+b+c)x+3λ(ab+bc+ac)=0

has real and distinct roots, then the value of λ is given by :

(a) λ<

3

4

(b)

3

11

<λ<

3

17

(c)

6

11

<λ<

4

15

(d) λ≥1

(b) If a,b are the roots of x

2

−10cx−11d=0 and c,d are the roots of x

2

−10ax−11b=0, then find the value, of a+b+c+d. (a,b,c,d are distinct numbers).
