1. 4x² - 12x = 32x²
2. 9m² - 16n² = 144m²n² ( in grade 7 & 8 )
3. 4a² + 12a + 9 = 288a² ( in grade 7 & 8 )
4. 2x² + 9x - 5 = 405x³
5. 27x³ - 8y³ = 216x³y³
6. a³ + 125b³ = 125a³b³
7. xm + hm - xn - hn = x²m²h²n² 
                               = h²m²n²x² ( alphabetical )

Factoring them:

1. 4x (x - 3)
2. (3m - 4m)(3m + 4m)
3. (2a + 3)²
4. Can't be factored.
5. (3x - 2y)(- 9x² + 6xy + 4y²)
6. (a + 5b)(a² - 5ab + 25b²)
7. m (h + x) - n(h + x) = (h + x)(m - n)
