campbell_st · Answer

well can you check its -10a^2   I think it should be -10a

campbell_st · Answer

which won't factor ....

campbell_st · Answer

like terms 

$$6a^2 - 10a^2 = -4a^2$$

campbell_st · Answer

so I have know idea what foil backwards can do... as the simplified expression won't factor

campbell_st · Answer

if the question is $$6a^2 - 10a + 3a - 5$$ this can be factored by grouping in pairs

$$(6a^2 + 3a) + (-10a - 5)$$

factor each pair of brackets

$$3a(2a + 1) -5(2a + 1)$$

now you can complete the factoring process. 

I think my expression is the correct 1
