Step-by-step explanation:

he zeroes of a polynomial 3x 2 -2x-5 are ______________

2) If and are the roots of quadratic equation x 2 +5x+a = 0 and 2 +5= -1

then a is

equal to

3) The graph of y = f(x), where f(x) is a quadratic polynomial meets the

x-axis at A(–2, 0) and B(–3,0), then the expression for f(x) is :

(a) x 2 +5x + 6 (b) x 2 - 5x + 6 (c)x 2 +5x- 6 (d) x 2 -5x– 6

4) The sum and product of the roots of 2x 2 – 5x + 4 = 0are in the ratio :

5) If one zero of the quadratic polynomial x 2 + 3x +k is 2 , then the value

of k is ____

6) If one root of the quadratic equation 4x 2 – 2x + (k-4) = 0 be the

reciprocal of the other, then k = ........

7) If the sum of the zeros of the polynomial f(x) =2x 3 -3kx 2 +4x-5 is 6, then

the value of k is __

8) The product of roots of a quadratic equation +7x-4=0 is

9) If the graph of the polynomial does not intersect x-axis, then the

number of zeroes of the polynomial is

10) If α and β are the zeroes of the polynomial 5x 2 – 7x + 2 ,then
