Question

If a and b are zero of the polynomial 2x2+5x-9 then the value is

Answer 1

Given: The correct question is If a and b are zero of the polynomial 2x^2 + 5x - 9 then the value of ab is?

To find: Value of ab?

Solution:

• Now we have given the equation: 2x^2 + 5x - 9.

• The roots are given as a and b.

• Now sum of roots are:

                 a + b = -5/2

• Now product of roots are:

                 a × b = -9/2

                 ab = -9/2

Answer:

                 So the value of ab is -9/2.

Answer 2

Answer:

answer is -9/2
