factorise
plz give me answer any three


I will give you brainlist ​

Answer 1

Step-by-step explanation:

a) 3x-9a

=3(x-3a)

Answer 2

Answer:

a)

3x - 9a

Factor 3 out of 3x and 9a

= 3(x - 3a)

b)

7x^3   -   14x^4

Factor 7x^3  out of  7x^3   -   14x^4

= 7x (1 - 2x)

c)

4xy + y^2

Factor y out of 4xy + y^2

= y(4x+y)

d)

24x^4  + 18x^3

Factor 6x^3 out of  24x^4  +  18x^3

= 6x^3 (4x  +  3)

e)

x^5 + x^3 -x

Factor x out of x^5 + x^3 -x

= x (x^4 + x^2 - 1)

f)

5x^3 yz  +  15xy^3 z  +  25xyz^3

Factor 5xyz out of  5x^3 yz  +  15xy^3 z  +  25xyz^3

= 5xyz (x^2 + 3y^2 + 5z^2)

Hope this helps
