Question

Solve equation. State the number and types of roots x^2-4x+40=0

Answer 1

How many roots will there be?

Answer 2

The number of roots is just the highest exponent of the variable in any of the terms. Note that in some cases, you can have 2 or more identical roots, so that it looks like there is only one solution, but in reality, there are multiple roots, and they simply have the same value. This is not such an equation, so there will be separate roots.
