Weegy: The GCF, [ or greatest common factor of variables is simple.
You look at all the variables separately and count them.
The lowest number will be your answer for that variable.
for example:
x x y y y z z AND x x x x z z z
look at the x's.
x x VS x x x x
there are two x's in the left term so the GCF, or your answer, of the x variable will be xx, or x^2
similarly, there are no y's in the right term, so there will be no y variable in the GCF.
finally, there are two z's in the left term and three z's in the right term.
therefore, there will be two z's in your GCF.
the final answer is the compilation of all the above

User: What is the product of (-a + 3)(a + 4)?
a2-a- 12
-a2-a- 12
-a2-a+ 12
a2-a+ 12
Weegy: (-a + 3)(a + 4)
= -a^2 -a + 12. choice C
User: Factor completely and then place the factors in the proper location on the grid.
a2 - a - 20
Weegy: a^2 - a - 20, the factors are (a-5)(a+4)
User: Factor y2 + 5y + 6.
(y+ 1)(y+ 6)
(y+ 2)(y+ 3)
(y+ 2)(y+ 4)
User: The area of a rectangle is found by multiplying the length by the width: A = lw. A certain rectangle has an area of x2 + 7x + 12.
Factor the trinomial to find the length and width of the rectangle.
l=x+ 6; w=x+ 2
l=x+ 5; w=x+ 7
l=x+ 4; w=x+ 3
Weegy: l = x + 4; w = x + 3
