Find two numbers that have a sum of 20 and a product of 64, please I need the the work and the way it was done

Answers

The two numbers will be such that their sum is 20 and the product is 64 are 16 and 4.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let’s say two numbers are x and y

Then,

Sum x + y = 20

Product xy = 64

Now, by substituting y = 20 – x into the second equation

x(20 – x ) = 64

20x – x² = 64

x² – 20x + 64 = 0

x² – 16x – 4x + 64 = 0

x(x-16) -4 (x – 16) = 0

(x – 4)(x – 16) = 0

x = 4 , 16

Hence “The two numbers will be such that their sum is 20 and the product is 64 are 16 and 4″.
