How do you do differentiation of polynomials?

Steps:
 #1: Identify the variable terms and constant terms in the equation.
 #2: Multiply the coefficients of each variable term by their respective exponents.
#3: Lower each exponent by one degree
#4: Replace the old coefficients and old exponents with their new counterparts.
#5: Find the value of the new equation with a given "x" value.

10 × 2 + 4 = 24. Hence, the required number is 24
