$\displaystyle 2x^4-162$

$\displaystyle 2(x^2-81)$

$\displaystyle 2(x^2-9^2)$

$\displaystyle 2(x-9)(x+9)$

Quote:

25z^3-36y^2z

$\displaystyle z(25z^2-36y^2)$

$\displaystyle z(5^2z^2-6^2y^2)$

$\displaystyle z[(5z)^2-(6y)^2]$

$\displaystyle z(5z-6y)(5z+6y)$ - Nov 30th 2006, 07:50 PMelfen_lied
oh and i need help on this problem also

6x^2+22xy-8y^2

edit:and this
