Answer 1

Answer:

Step-by-step explanation:

y^2-6y+9

Using Middle Term Splitting

We have to find 2 numbers whose sum is -6 and product is 9 and the numbers are -3 and -3

y² - 3y - 3y +9

= y(y-3) - 3(y-3)

= (y-3)(y-3)

So it is the whole square of y-3

So the factors/solutions of the equation are 3 and 3
