Answer:
Ans = 40L - L²
Step-by-step explanation:
Let the L be the larger number and S the smaller number
the sum of two numbers is 40 can be represented as:
L + S = 40-----------------(1)
From (1), make S subject of formula:
S = 40 - L------------------(2)
express the product of the two numbers in terms of L
product of the two numbers = L*S
Substituting S = 40 - L from (2)
L*S = L (40-L)
= 40L - L²
