Question

Which is a factor of both terms of the expression 2d−10?

Answer 1

2 would be the answer

Answer 2

Answer:

2

Step-by-step explanation:

Remember that a factor is something that can be divided out by all the terms in the system. You cannot divide a number (10) with a variable (letter) so the top two won't work. You cannot divide 2 by 10 because it results in a fraction/decimal so 2 is the only answer. You can factor out 2 in the system so it will be 2(d-5).
