-3•-4=12, and -3+-4=-7.
this will turn into
(x-3)(x-4)
set them up to equal zero
x-3=0, x-4=0
solve
x=3, x=4
(a)
Answer:
Step-by-step explanation:
Lets try to simplify each to check which one is incorrect so it will be NOT true
first one is :
distribute the exponent so :

CORRECT
Second one is :
CORRECT because anything raised to exponent 0 is 1 .
Last one is :

so Last is<em> INCORRECT</em>
