Question

If the sum of zeros of the polynomial 5x²+3x+k is -11/25 find the value of k

Answer 1

Answer:

The correct option is: (A) 3, 5 Explanation: Sum of zeroes of polynomial Now, 2x2 -2(k+ 11)x + 30 becomes 2x2 - 16x + 30. i.e.,2x2 - 16x + 30 = 0 or x2 - 8x + 15 = 0 => x = 3,5 Hence, zeroes of polynomial 2x2 - 16x + 30 are 3, 5. ← Prev QuestionNext Question → Related questions 0 votes 1 answer If α, β are zeros of polynomial p(x) = 2x^2 + 5x + k which satisfies the relation α^2 + β^2 + αβ = 21/4, asked May 9, 2020 in Polynomials by VinodeYadav (35.7k points) polynomials class-10 0 votes 1 answer If α and β are zeros of polynomial f(x) = x^2 – 5x + k such that α – β = 1, then find k. asked May 9, 2020 in Polynomials by VinodeYadav (35.7k points) polynomials class-10 0 votes 1 answer If α and β are the zeros of the polynomial f(x) = x^2 ‒ 5x + k such that α ‒ β = 1, find the value of k. asked Apr 10, 2020 in Polynomials by Vevek01 (47.2k points) polynomials class-10 0 votes 1 answer Find all the zeros of the quadratic polynomial 5x^2 + 8x - 4 = 0 asked Jan 26 in Polynomials by Abdul Mannan (15 points) class-10 polynomials 0 votes 1 answer If (a - b) , a and (a + b) are zeros of the polynomial 2x^3 - 6x^2 + 5x - 7 write the value of a asked 4 days ago in Polynomials by Gavya (19.2k points) polynomials class-10 Read more on Sarthaks.com - https://www.sarthaks.com/248662/if-sum-of-all-zeros-of-the-polynomial-5x-2-3-k-x-7-is-zero?show=248666#a248666
