If you mean:
5x2 + 10x + 40
Then the only factoring you can do is to divide it by five:
5(x2 + 2x + 8)
beyond which it can not be factored.
If on the other hand you mean:
5x2 + 10x - 40
Then you can factor it out as follows:
5x2 + 10x - 40
= 5(x2 + 2x - 8)
= 5(x2 - 2x + 4x - 8)
= 5(x(x - 2) + 4(x - 2))
= 5(x + 4)(x - 2)
5(x + 4)(x - 2)
10(x+4)
10x plus 40 is 50x.10+40=50 and then you just add the x so:10x+40=50x
10(x + 4)
10(x + 4)
I need to; factor each expression 10x + 40 = ?
Y = 10x 10x = 40 y = 40
10 + 40 = 5050 / (5x2) = 50/1050/10 = 5
The equation 10x - 15x + 5 = -45 + 40 can be simplified to -5x + 5 = -5. By moving the numbers to one side, it becomes -5x = -10, to 5x = 10, then x = 2.
Depends on the value of x if x is 1 then 10x + 20 = 30 if x is 2 then 10x + 20 = 40 if x is 3 then 10x + 20 = 50 if x is 4 then 10x + 20 = 60 if x is 5 then 10x + 20 = 70 if x is 10 then 10x + 20 = 120 And so on
(x2 plus 40) (x minus 1)
5(x=8)
