9m2-6/5m+c is a perfect square what is the value of c

The expression given to us is:

If the above expression is a perfect square then the middle term will have to be 2 times the square root of the first term times the square root of the last term. Thus:

Thus,

Thus, for 9m^2-(6/5)m+c to be a perfect square, the value of c must be equal to or 1/25

c

-by-step explanation:

it would be c

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
