Answer 1

Answer:

I can't understand this one sorry

Answer 2

given polynomial : 9x^2 +6x + 1

now by splitting Middle term

9x^2 + 3x + 3x + 1

= 3x ( 3x + 1) + 1 ( 3x + 1)

= ( 3x + 1) ( 3x + 1)

either x = -1 /3 or x = -1/3

.

.

now to find relationship we know that.....

alpha + beta = -b /a

-1/3 -1/3 = -6/9

-2 / 3 = -2/3

alpha * beta = c/a

-1/3 * -1 /3 = 1 /9

1/9 = 1/9

hence proved
