Question

If (2x-3) is a factor of 2x^4 - 3x^2 +15x -15k,
find the value of ( 3k- root 5)
pls help

​

Answer 1

Step-by-step explanation:

If 2x-3 is.

put x=3/2 then

2(3/2)^4 - 3(3/2)^2 + 15(3/2) -15k =0

81/8 - 81/ 4 + 45/2 =15k

(-81 + 180) / 8 =15k

99/8 =15k

then k= 99/120

3k - 5^1/2

99/40-5^1/2

Answer 2

Answer:

2.939

Step-by-step explanation:

Given that, 2X -3 is a factor of the equation

so we can write 2X-3=0

Hence, X=3/2
