The values of x are 1 and - 1
The intersect method would use the graphs of both equations to find points where they would cross each other. In this instance, the graphs would cross each other at two points
Let's solve the equation:
Rearrange all nonzero terms to the left side of the equation:
x² - 3 + x² - 1 = 0
Combine like terms:
2x² - 2 = 0
Reduce the greatest common factor on both sides of the equation:
x² - 1 = 0
Factor the expression using :
a² - b² = ( a + b) ( a- b) : ( x - 1) ( x + 1) =0
Apply Zero Product Property:
x + 1 = 0 or x -1 = 0
Rearrange unknown terms to the left side of the equation:
x = - 1
Rearrange unknown terms to the left side of the equation:
x = 1
Thus, the values of x are 1 and - 1
