Question

A) if x =
3/
2
is a solution of the quadratic equation 4x
2 + mx − 3 = 0, find the value of m.

Answer 1

Step-by-step explanation:

4(3/2)+2+m(3/2)-3=0

6+2+3/2m-3=0

5+3/2m=0

3/2m=-5

m=-10/3

Answer 2

Answer:

-4 is the answer

Step-by-step explanation:

4(3/2)²+m(3/2)-3=0

4(9/4)+3m/2-3=0

9+3m/2-3=0

3m/2+6=0

3m/2=-6

3m=-6*2

3m=-12

m=-12/3

m=-4
