#### Important Questions – Polynomials

- What real number should be subtracted from the polynomial 3x³ + 10x² – 14x + 9, so that the polynomial 3x – 2 divides it exactly? [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]
- Write a quadratic polynomial, the sum of whose zeroes is – 3 and their product is also – 3.
- 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]

###### Questions for Practice
