Question

If one zero the quadratic polynamal 2x^-3x+p is 3, find the value of p . also of the other zero​

Answer 1

Answer:

The value of p is -9.

Two roots are 3 and -3/2

Step-by-step explanation:

Let f(x) = 2x²-3x+p

Given, 3 is one of the zeroes of f(x).

• f(3) = 0

=> 2(3)²-3(3)+p = 0

=> 18-9+p = 0

=> p = -9

Now,

• f(x) = 2x²-3x-9

=> 2x²-6x+3x-9

=> 2x(x-3)+3(x-3)

=> (x-3) (2x+3)

(2x+3) = 0

x = -3/2

Thus, other zero of the polynomial is -3/2.
