Factor the expression. 8x + 2?

2 (4x + 1)

2(4x+1)

2(4x+1)

2(4x+1)

think of roughly how FOIL works. you may want 2 numbers that, whilst superior mutually, supply you +sixteen. yet whilst further mutually, they could desire to equivalent -8. those numbers are -4 and -4. So, you may set up the aspects like this: (x-4)(x-4) and then use FOIL to be taught and verify that's the splendid answer.

8x + 2
= 2(4x + 1)

The common factor is 2, so take it out...
2(......)
Then Divide the 8x and 2 by 2...
8x/2=4x, 2/2=1
So the answer is...
2(4x+1)

8x+2=2(4x+1) or 8(x+1/4)

too easy...

The common factor is 2, so take it out...
2(......)
Then Divide the 8x and 2 by 2...
8x/2=4x, 2/2=1
So the answer is...
2(4x+1)
