Question

factor this expression completely
45x-18y+36

Answer 1

To factor the expression 45x - 18y + 36 completely, we need to look for common factors. Firstly, we can see that all the terms have a common factor of 9:

45x ÷ 9 = 5x
-18y ÷ 9 = -2y
36 ÷ 9 = 4

So, the expression can be factored as:

45x - 18y + 36 = 9(5x - 2y + 4)
