Value of c = 2 as per the given polynomial.
" A polynomial is an algebraic expression which consists of one or more than one terms with the coefficient."
According to the question,
p(x) = cx³ - 15x -68
p(x) is divisible by (x-4)
Therefore ,
For x =4
p(4) = 0
Substitute the value in the given polynomial
p(4) = c(4)³ - 15 (4) -68
⇒0 = 64c - 60-68
⇒ c= 2
Hence, the Value of c = 2 as per the given polynomial.
