Standard Representation - Examples, Exercises and Solutions

Find the standard representation of the following function

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

We will use the expanded distributive property.

(a+1)⋆(b+2) = ab+2a+b+2

Let's substitute the given values and solve:

(x-2)(x+5) =

x²-2x+5x+-2*5=

x²+3x-10

And that's the solution!

$f(x)+x^2+3x-10$
