x = 4 and x = –4
x = 8 and x = –8
x = 16 and x = –16
The correct statement is that the solution of this equation x² – 16 = 0, is 4 and -4.
It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation. The general form of the quadratic equation is ax² + bx + c = 0
Given
The quadratic equation x² – 16 = 0
To find
The root of the quadratic equtaion?
The quadratic equation x² – 16 = 0
We know the formula,
a² - b² = ( a - b ) ( a + b )
Then
x² – 4² = 0
(x - 4)(x + 4) = 0
x = 4 and -4
Thus, the solution of this equation x² – 16 = 0, is 4 and -4.

Answer: The correct option is (B) x = 4 and x = -4.
Step-by-step explanation: We are given to find the solutions to the following quadratic equation :
Since the coefficient of x is zero in the given equation, so we will be using the method of square root to solve the equation.
From equation (i), we have
Thus, the required solution is x = 4 and x = -4.
Option (B) is correct.
The other endpoint will be equal to (-7, -2).
A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that the midpoint of cd is e ( -1,0 ) one endpoint is c( 5,2 ). The midpoint will be calculated as:-
Midpoint = (x₁+x₂ / 2 , y₁+y₂ / 2)
5 + x₂ / 2 = -1
5 + x₂ = -2
x2 = -7
2 + y₂ / 2 = 0
2 + y₂ = 0
y₂ = -2
Therefore, the other endpoint will be equal to (-7, -2).
