Maths help please, factorising.?
Please could you help?
Factorise completely
1) 2a^2+a
2) 8x^3y^2-4xy^3
Thankyou :)
yes, the second one is written exactly
as I have put it.
It confused me too, that's why I needed
help with it.
Thankyou to everyone who has helped

1) Both terms are divisible by a:
a(2a+1)
2) Both terms are divisible by 4xy^2:
4xy^2(2x^2-y)

1)
2a^2+9
2a^2=9
2a=sqrt(9)
a=3/2
a= 3/2 = 1.5
2)
you need to re write question 2 with () so we know how the question is worded.

2a^(2)+a
Factor out the GCF of a from each term in the polynomial.
a(2a)+a(1)
Factor out the GCF of a from 2a^(2)+a.
a(2a+1)
8x^(3)y^(2)-4xy^(3)
Factor out the GCF of 4xy^(2) from each term in the polynomial.
4xy^(2)(2x^(2))+4xy^(2)(-y)
Factor out the GCF of 4xy^(2) from 8x^(3)y^(2)-4xy^(3).
4xy^(2)(2x^(2)-y)
