Answer :
[tex]2a^2-32[/tex]
[tex]2*a^2-2*16[/tex]
[tex]2*(a^2-16)[/tex]
but we have a Difference of two square
[tex]x^2-y^2=(x+y)*(x-y)[/tex]
now you can see it very well
[tex]2*(a^2-4^2)[/tex]
so
[tex]\boxed{\boxed{2*(a-4)*(a+4)}}[/tex]
[tex]2*a^2-2*16[/tex]
[tex]2*(a^2-16)[/tex]
but we have a Difference of two square
[tex]x^2-y^2=(x+y)*(x-y)[/tex]
now you can see it very well
[tex]2*(a^2-4^2)[/tex]
so
[tex]\boxed{\boxed{2*(a-4)*(a+4)}}[/tex]
