Question 578557
I have no clue how to work these.  I can do the basic ones but can't figure these out in order to help my daughter.  Thanks!
 
45x<sup>4</sup> - 60x<sup>2</sup>y + 20y<sup>2</sup>
 
5(9x<sup>4</sup> - 12x<sup>2</sup>y + 4y<sup>2</sup>)
 
5(3x<sup>2</sup> - 2y)(3x<sup>2</sup> - 2y)
 
5(3x<sup>2</sup> - 2y)<sup>2</sup>
 
---------------------
 
37(g<sup>8</sup> - h<sup>8</sup>)
 
37[(g<sup>4</sup>)<sup>2</sup> - (h<sup>4</sup>)<sup>2</sup>]

 
37[(g<sup>4</sup> - h<sup>4</sup>)(g<sup>4</sup> + h<sup>4</sup>)]


37(g<sup>2</sup> - h<sup>2</sup>)(g<sup>2</sup> + h<sup>2</sup>)(g<sup>4</sup> + h<sup>4</sup>)


37(g - h)(g + h)(g<sup>2</sup> +h<sup>2</sup>)(g<sup>4</sup> + h<sup>4</sup>)
