Answer:
B. (x - 6)(x + 2).
Step-by-step explanation:
x^2 - 4x - 12
We need 2 numbers whose product is the last number -12 and whose sum is the coefficient of x (-4).
These numbers are -6 and + 2.
So the factors are (x - 6)(x + 2).
Answer:
-1
Step-by-step explanation:
the additive inverse of -5is5 because (-5+5=0) &
the multiplicative inverse of -5is 1/-5. because (-5*1/-5=1)
therefore 5*1/-5=5/1*1/-5
=5/-5
=-1
