Answer: 16a + 32b - 8c
Step-by-step explanation:
8(2a + 4b - c ) = 16a + 32b - 8c
Multiply 8 by 2a to get 16a
Multiply 8 by 4b to get 32b
Multiply 8 by -c or -1c to get -8c
Put them together to get 16a + 32b - 8c
Funny... I'm doing a lesson on factoring right now :)
The Greatest Common Factor would be 4, the biggest number that divides into all of them evenly. You would factor out the 4.
4(x² - 4x + 2)
Hope this helps!!!
The trick here is to notice that all 3 terms can be div. by 2:
2(x^2 + x - 12)
Note that -12 factors into -3 * 4 or -4 * 3. Thus,
x^2 + x - 12 = (x-4)(x+3), and so <span>2x2 + 2x − 24 = 2(x-4)(x+3).</span>
