Question

If 3x2 – 2kx + m = 0, find k when x = 2 and m = 3.

Answer 1

Hi mate

Here is ur answer⬇️⬇️

3x^2 - 2kx + m = 0

3(2)^2 - 2(2)k + 3 = 0

3(4) - 4k + 3 =0

12 + 3 -4k = 0

-4k=-15

➡️k=15/4

I hope this will help you

Here is the full solution....

3x^2-2kx+m = 0

x = 2 and m = 3

now putting the value of "x" and "m" ――――

3(2)^2 - 2k(2) + 3 = 0

3×4 - 4k + 3 = 0

12 + 4k + 3 = 0

4k = -12 - 3

4k = - 15

k = -15/4 answer...

Hope this'll will help you buddy
