6a² + 7ax - 3x²
6a² + 9ax - 2ax - 3x²
3a(2a) + 3a(3x) - x(2a) - x(3x)
3a(2a + 3x) - x(2a + 3x)
(3a - x)(2a + 3x)
First of all, to simplify expressions we use the PEMDAS
then we do the right needed inverse to move the variables all to one side and the other numbers to another... this is a way we simplify expressions
Hope this helps :)
When : 36 ÷ n = 4
10) n = 9
Plug in 9 for n
36 ÷ 9 = 4
Correct / true
11) n = 6
Plug in 6 for n
36 ÷ 6 = 4
Incorrect / false
12) n = 5
Plug in 5 for n.
36 ÷ 5 = 4
Incorrect / false
~Hope I helped!~
