Does anyone have the solution to this

Step-by-step explanation:

There is 1 root at x = 1, where the function crosses the x-axis.

There are 2 roots at x = -2, where the function touches the x-axis but does not cross.

So there are 3 real roots total.

The function is:

y = (x − 1) (x − (-2))²

y = (x − 1) (x + 2)²

It is a diagram that is used to split down the number into it's divisible factors until all the Factors are prime. The first way you can use this is to divide out prime numbers one by one

Hope this helps =)
