Examples with solutions for Product Representation: Transition between different representations of a function

Exercise #1

Find the standard representation of the following function

$f(x)=(x-2)(x+5)$

Video Solution

Step-by-Step Solution

We will begin by using the distributive property in order to expand the following expression.

(a+1)⋆(b+2) = ab+2a+b+2

We will then proceed to insert the known values into the equation and solve as follows:

(x-2)(x+5) =

x²-2x+5x+-2*5=

x²+3x-10

And that's the solution!
