Answer 1

Step-by-step explanation:

• State whether the following statements are true or false : (9. nos. 1 to 4)

1. If 2 is one of the zeroes of the polynomial p (x) = x2 - 9x + k, then k = 14.

2. The discriminant of the equation x2-3x - 8 = 0 is - 23.

3. # is a rational number.

4. If (a, 7) is one of the solutions of equation 3x + 2y = 41, then a = 9.
