Question

what are the solutions to the quadratic equation x2 – 16 = 0?

x = 2 and x = –2
x = 4 and x = –4
x = 8 and x = –8
x = 16 and x = –16

Answer 1

If you would like to find the solutions to the quadratic equation x^2 - 16 = 0, you can do this using the following steps:

x^2 - 16 = 0
(x - 4) * (x + 4) = 0
x^2 + 4x - 4x - 16 = 0
1. x = 4
2. x = - 4

The correct result would be x = 4 and x = –4.

Answer 2

The solution to the system of equation is x = ±4

Solution to quadratic functions

Quadratic functions are functions that have a leading degree of 2.

Given the quadratic equation

x^2 – 16 = 0

We are to find the solution to the given quadratic equation.

Add 16 to both sides

x^2 - 16 + 16 = 0 + 16
x^2 = 16

Take the square root of both sides

x= √16
x = ±4

Hence the solution to the system of equation is x = ±4
