Question

If x=-2 and x=3 are the solution of quadratic equation 3x^+2kx+2m find the value of k and m .​

Answer 1

Answer:

In the quadratic equation 3x^2 - 2kx + 2m=0, by Newton's theorem, sum of roots is 2k/3 and product of roots is 2m/3. Thus 2k/3 = 5 hence k= 7.5 and 2m/3 = 6 hence m = 9.

Answer 2

Answer:

k=-1/2 , m=-3

Step-by-step explanation:

(-2k) = -2 + 3 => k = -1/2

2m = -2 × 3 => m=-3

by relation between roots and coefficients
