If you had to subtract 426 from 913, how many times would you need to regroup? how can you tell?

1 answer:

5 0

Regrouping in subtraction means that if you can't subtract because the digit on the bottom has a greater value than the digit on the top (such as 3-6)m so in this case you would have to regroup twice.

How do I factor 8x^2+12+48?

wolverine [178]

We can factor a 4 out of this expression.

4(2x^2 + 3x + 12)

Now that the expression is simplified, we can see if splitting the middle term is possible.

<em><u>Display factors of 24.</u></em>

1 * 24

-1 * - 24

2 * 12

-2 * -12

3 * 8

-3 * - 8

4 * 6

-4 * -6

All factors of 24 have been listed, and none of these digits satisfy the criteria.

Trinomial cannot be further factored.
