Answer:
The possible value of q is [tex]25[/tex]
Step-by-step explanation:
step 1
we have
[tex]2x^{2} +5x-q=0[/tex]
If 2.5 is a root of the equation
then
substitute the value of x=2.5 in the equation and solve for q
[tex]2(2.5)^{2} +5(2.5)-q=0[/tex]
[tex]12.5 +12.5-q=0[/tex]
[tex]25-q=0[/tex]
[tex]q=25[/tex]
