Answer 1

Step-by-step explanation:

Let the same factors be a

x^2-cx+(81/16)

=16x^2-16cx+81=0

Sum=(-b/a)

a+a=[(-(-c)/16]

2a=(c/16)

a=(c/32)---(equation 1)

Product=(c/a)

a×a=(81/16)

a^2=(81/16)

a=(9/4) or 2.25--(equation 2)

putting a=(9/4) in equation 1

(9/4)=(c/32)

(9×32)/4=c

(9×8)=c

c=72
