Question

if a and B are the zeros of the quadratic polynomial 2x2 - X- 1. then the value of + ] is
d)-
1
a) s
b) 5
c) 3​

Answer 1

answer:

17

Step-by-step explanation:

a=coefficient of x²

b=coefficient of x

c=constant term(according to the quadratic polynomial these value are given)

so,

a=2

b=5

c=1

(a+b)+ab

(2+5)+2*5

(7)+10

7+10

17 answer
