What value of c makes the polynomial below a perfect square?
malfutka [58]

Answer:

B

Step-by-step explanation:

x² + 9x

to complete the square

add ( half the coefficient of the x- term )² to x² + 9x

= x² + 2(\frac{9}{2} )x + (\frac{9}{2} )²

= x² + 9x + \frac{81}{4} ← the value of c

= (x + \frac{9}{2} )² ← a perfect square
