Question

❣️❣️HLO GUYS! ❣️❣️
NOT FOR SPAMMERS!!

Find a cubic polynomial with the sum, sum of the product of its zeroes taken two at a time, and the product of its zeroes as 2, -7, -14 respectively.


PlzZ don't try to spam bcaz I need answer of this question quickly and right.

Answer 1

hey mate here is ur answer =

Sum of roots =2

roots taken two at a time = -7

product =-14

formula= x^3-(sum of roots)x^2+(sum of product of two roots taken at a time)x-product of roots=0

so cubic equation = x^3-2x^2-7x+14

so this is ur answer .

pls mark as brainliest I need it .

have a good day.

Answer 2

Answer:

• Here it is....
• This question can be solved a/c to the formula for cubic polynomial. -
• x^3-(a+B+y)x^2 +(aB+By+ya)x -(aBy)

• x^3-2x^2-7x+14
• You can see as sum of the products, and sum of the product of its zeroes taken two at a time, and the product of its zeroes

are given so u only have to put them in the formula accordingly.
