What value of c makes x2 + 6x + c a perfect square trinomial?

c=9

Step-by-step explanation:

The given polynomial is a perfect square trinomial.

using completing square method to find the perfect square.

Now we compare the given polynomial

2ab=6x

b=3

But

So, c=9

Hence, The value of c is 9 to make perfect square.

answer:

what is your question that you ask

step-by-step explanation:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
