Question

X²-4=0 can you help me solve for x?​

Answer 1

Explanation:

X²-4=0

x² = 4

x =√4 or x = - √4

x = 2 or x = -2

Answer 2

• x = 2 & - 2

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.

• x²-4=0

Step: Solve the problem by spiltting method.

• x² - 4 = 0
• x² - (2)² = 0

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.
