###### Polynomials for Class 10 – Maths

- If one zero of the quadratic polynomial (k² + k) x² + 68x + 6k is reciprocal of the other, find k. [Answer: 5]
- If α and β are the zeroes of the polynomial x² – 5x + m such that α – β = 1, find m. [Answer: 6]
- If the sum of squares of zeroes of the polynomial x² – 8x + k is 40, find the value of k. [Answer: 12]
- If α and β are zeroes of the polynomial t² – t – 4, form a quadratic polynomial whose zeroes are 1/α and 1/β. [Answer: 4t² + t – 1 = 0]
- If (k + y) is a factor of each of the polynomial y² + 2y – 15 and y³ + a, find values of k and a. [Answer: k = 3, -5 and a = 27, -125]
- Obtain zeroes of 4√3x² + 5x – 2√3 and verify relation between its zeroes and coefficients. [Answer: -2/√3, √4/4]
- If x4 + 2x³ + 8x² + 12x + 18 is divided by (x² + 5), remainder comes out to be (px + q), find values of p and q. [Answer: p = 2, q = 3]
