1.	The quadratic polynomial, the sum of whose zeroes is –5 and their product is 6, is(a) x2 + 5x + 6 (b) x2 – 5x + 6 (c) x2 – 5x – 6 (d) –x2 + 5x + 6
Answer» The correct option is (a) x² + 5x + 6. Quadratic polynomial = x² – (sum of zeroes)x + product of zeroes = x² – (–5)x + 6 = x² + 5x + 6

The quadratic polynomial, the sum of whose zeroes is –5 and their product is 6, is(a) x2 + 5x + 6 (b) x2 – 5x + 6 (c) x2 – 5x – 6 (d) –x2 + 5x + 6

Answer»

The correct option is (a) x² + 5x + 6.

Quadratic polynomial

= x² – (sum of zeroes)x + product of zeroes

= x² – (–5)x + 6

= x² + 5x + 6
