Question

what What should be added to (1/-2 -1/4of -8/15) so that the sum is the product of-7/50 and 1 1/14 ?​

Answer 1

HELLO MATE

HERE IS YOUR ANSWER

LET THE NUMBER BE ' x '

( -1/2 - 3/4 of -8/15 ) + x = -7/50 * 15/14

( -1/2 -3/4 * -8/15 ) + x = -105/700

( -1/2 + 24/60 ) + x = -105/700

-30 + 24 / 60 + x = -105/700

-6/60 + x = -105/700

-1/10 + x = -21/140

-1/10 + x = -3/20

x = -3/20 + 1/10

x = -3 + 2 / 20

x = -1/20

HOPE IT HELPS.

Answer 2

Answer:

Let the polynomial be ax

3

+bx

2

+cx+d and the zeroes be α,β,γ.

Sum of the polynomial = α+β+γ=

1

2

=

a

−b

Sum of the product of its zeroes taken two at a time = αβ+βγ+αγ=

−7

=

a

c

Product of the root = αβγ=

−14

=

a

−d

If a=1,b=−2,c=−7,d=14.

Hence the polynomial is x
