Factorise 20a+30a^2 maths

[From: ] [author: ] [Date: 11-05-05] [Hit: ]
-Well you can take 10a out for a start.did you mean 16ay^2 + 24y^2?If you meant what you typed.Hope this helps.......
I don't see any two factor pairs of 30 that add to give 20, I suppose it's something to do with squaring outside of a bracket but I don't know how, any help please, Thanks.

1. Factor the expression by 10a to get:

10a(2 + 3a)

2. Factor the expression by 8ay to get:

8ay(2y + 3a)

I hope this helps!

With the other one how about

did you mean 16ay^2 + 24y^2?

that's 8y^2 (2a + 3)

If you meant what you typed.

16y^2 + 24^2 y = 16y^2 + 576y this factorises to 16y (y + 36)

Hope this helps.

20a + 30a² = 10a(2 + 3a)

16ay² + 24a²y (I assume this what you meant)
= 8ay(2y + 3a)
