What are Integers?

The integers (from the Latin integer, which means with untouched integrity, whole, entire) are the set of numbers consisting of the natural numbers including 0 (0, 1, 2, 3, ...) and their negatives (0, −1, −2, −3, ...). They are numbers that can be written without a fractional or decimal component, and fall within the set {... −2, −1, 0, 1, 2, ...}. For example, 65, 7, and −756 are integers; 1.6 and 1½ are not integers. In other terms, integers are the numbers one can count with items such as apples or fingers, and their negatives, including 0.

Which equations are true for x = –2 and x = 2? Select two options

yulyashka [42]

The equations that are true for x = -2 and x = 2 are $x^{2}$ -4 = 0 and 4 $x^{2}$ = 16

<h3>What is an equation?</h3>

An equation is a mathematical statement that establishes the equality of two quantities.

Analysis:

Testing the equation x2 - 4 = 0

for x = 2, $(2)^{2}$ - 4 = 4-4 = 0

for x = -2 = (-2)2 - 4 = 4-4 = 0

Therefore x2-4 = 0 is true

Testing for 4x2 =16

for x = 2 , 4(2) ^2 = 4x4 = 16

for x = -2 4(-2)^2 = 4(4) = 16.

All other equations are not true except these two.
