Answer:
The Identity property of addition
Step-by-step explanation:
The identity property of addition states that any number plus zero equals the original number. So, since 0 is being added to 6, it must still be equal to 6. This property works for any number, which is why it works as a property.
This is not to be confused with the identity property of multiplication that states that any number times 1 equals the original number.
X^2+34=74
minus 34 from both sides
x^2=40
sqrt both sides
x=+/-√40
x=+/-2√10
the values 2√10 and -2√10 are soltuions for x
