Question

If a and b are zeroes of polynomial x^2 + 7x + 7 , find the value of a^-1 + b^-1

Answer 1

Step-by-step explanation:

so answer is -1....,.....

Answer 2

Answer:

a^-1=1/a and b^-1=1/b

Step-by-step explanation:

so,

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

a/q a+b=-7/1

ab=7

putting values in equation [1]

hence, answer is -7/7=-1
