Answer 1

Answer:here are some formulas!!hope this will help you

plz mark in brainliest!(if its helpful)

Answer 2

Relationship ship between zeroes and coefficients for quadratic polynomial

Sum of zeroes(alpha+beta)

=-(coefficient of x) _____________

Coefficient of x2

Product of zeroes(alphaxbeta)

=constant term

__________

Coefficient of x2

For finding quadratic polynomial formula:

K[x2-(alpha+beta) x+alpha×beta]

Relationship ship between zeroes and coefficients for cubic polynomial

Sum of zeroes(alpha+beta+gamma)

=(coefficient of x2)

______________

Coefficient of x3

Product of zeroes(alpha×beta×gamma)

=-(constant term)

_____________

Coefficient of x3

Sum of the product of zeroes taken at a time =

alpha×beta+beta×gamma+gamma×alpha

=coefficient of x

____________

Coefficient of x3

For finding cubic polynomial formula=

K[x3-(alpha+beta+gamma)x2+(alpha×beta+beta×gamma+gamma×alpha)x-alpha×beta×gamma)]

P(x)=g(x)×q(x) +r(x)

I hope it's help you
