Question

Which formula is used to find cubic polynomial if sum , sum of product and product is given ??​

Answer 1

Answer:

A cubic polynomial is the polynomial whose degree is 3 and it has 3 roots. We will use the sum, sum of the products and products given in the question to find the cubic polynomial. sum of products = α+β+γ=−ba, where b is the coefficient of x2 and a is the coefficient of x3.

$Let \: the \: polynomial \: be  \: ax^{3} +bx^{2} +cx+d  \: and \: the \: zeroes \: be \:  α,β,γ.$

$Sum \: of \: the \: polynomial = α+β+γ=\frac{ - b}{a}$

$Sum \: of \: the \: product \: of \: its \: zeroes \: taken \: two \: at \: a \: time = αβ+βγ+αγ = \frac{c}{a}$
