Answer:
Step-by-step explanation:
We have to find the value of x from the given equation.
- x²-4=0 is a quadratic equation, so it will have two values.
Step: Write the equation in simplest form.
Step: Solve the problem by spiltting method.
Step: Solve the problem with using algebraic formula.
- x² - 2² = 0
- (x - 2)(x + 2) = 0
Step : We have used a²-b² to solve the problem.
- (x - 2)(x + 2) = 0
- (x - 2)(x + 2) = 0
- (x - 2)=0 or (x + 2) = 0
- x = 2 & - 2
Therefore, the possible values of x are 2 & - 2.
