Question

If one zero of 2x^2x-3x+k is reciprocal of other,find k=?​

Answer 1

Answer:

Given a quadratic equation:2x² – 3x + k

Also given one of the zeros of 2x² – 3x + k is reciprocal to the other,

We need to find the value of k.

Solution

Let us assume that one zeros of the given quadratic equationbe(2x² – 3x + k) be α

Hence the other zero is reciprocal of the zero. So the other zero is 1/α

As per the given equation

a = 2 b = -3 c = k

So, α x 1/α = c/a

1 = k/2

k = 2

The value of k is 2

Answer 2

Answer:

2X²-3X+k

suppose. 2X²-3X+k = 0

= 2X²+k = 3X

= k = 3X-2X²

= K=X

then K=X.
