Answer:

4

Step-by-step explanation:

To find the number of real roots of the given factored polynomial, all we have to do is to count its factors. It's not necessary to expand it.

"x" counts as one factor.

"(x-1)^2" counts as two factors since this is squared.

"(x+2)" counts as one factor.

Adding them, 1 + 2 + 1 = 4 factors.

Thus, the equation has 4 real roots.

Hope this helps!
