Hope you like the answer

Step-by-step explanation:

Let x = the number

x+x = x*x

2x= x^2

This is a quadratic equation, so you have to set it equal to zero. To keep the x^2 term positive, let's subtract 2x from each side, as follows:

Subtract 2x from each side:

0=x^2-2x

Factor out the common factor of x:

0=x(x-2)

x=0 or x-2=0

x=0 or x=2

Look for "Rapalje Homepage" near the top of these searches. Then near the top of my Homepage, look for "Basic, Intermediate and College Algebra". Choose "Basic Algebra", "Chapter 2", "Section 2.09 Quadratic Equations". See also the "MATH IN LIVING COLOR" pages that go with this section.
