Web6 Jul 2014 · Relationship between the zeroes and coefficients of a cubic polynomial • Let α, β and γ be the zeroes of the polynomial ax³ + bx² + cx • Then, sum of zeroes(α+β+γ) = -b = … The sum of zeroes = -coefficient of x /coefficient of x 2. Now, substitute the values in the formula, we get. Sum of zeroes = -(-16)/9 = 16/9. Similarly, Product of zeroes = constant term / coefficient of x 2. Plugging the values in the above formula, we get. Product of zeroes = 20/9 See more A zero of a polynomial p(x) is the value of x for which the value of p(x) is 0. If k is a zero of p(x), then p(k)=0. For example, consider a polynomial p(x)=x2−3x+2. When x=1, the value of p(x) will be equal to p(1)=12−3×1+2 … See more Quadratic polynomials can be factorized by splitting the middle term. For example, consider the polynomial 2x2−5x+3 Splitting the middle term: The middle term in the polynomial 2x2−5x+3 is -5x. This must be expressed as … See more For Quadratic Polynomial: If α and β are the roots of a quadratic polynomial ax2+bx+c, then, α + β = -b/a Sum of zeroes = -coefficient of x … See more Let us assume that P(x) and G(x) are the two polynomials, such that G(x)≠ 0, then the division algorithm states the formula to find Q(x) and R(x) … See more imf india populationWebZeroes of a Cubic Polynomial. Any such polynomial will have, in general, three zeroes. For example, p(x): x3 −6x2 +11x−6 p ( x): x 3 − 6 x 2 + 11 x − 6 has the following three zeroes (verify that these are indeed the zeroes of the polynomial): x = 1, 2, 3 x = 1, 2, 3.
