Steven will factor the expression 42xyz + 56xy – 7x by dividing each term by a common factor. Which possible common factor could Steven use? (choose 2)
Responses
A 77
B yy
C zz
D xx
E 6
The possible common factors that Steven could use are:
A) 77: Since none of the terms in the expression are divisible by 77, it is not a possible common factor.
B) yy: Since none of the terms in the expression have a factor of yy, it is not a possible common factor.
C) zz: Since none of the terms in the expression have a factor of zz, it is not a possible common factor.
D) xx: Each term in the expression has a factor of x, so x could be a possible common factor.
E) 6: Each term in the expression has a factor of 2, so 2 could be a possible common factor.
