Type your math problem... x^2-24

Question

Find the roots

x_{1} = - 26, x_{2} = 26

Alternative Form

x_{1} \approx - 4.898979, x_{2} \approx 4.898979

Evaluate

x^{2} - 24

To find the roots of the expression,set the expression equal to 0

x^{2} - 24 = 0

Move the constant to the right-hand side and change its sign

x^{2} = 0 + 24

Removing 0 doesn't change the value,so remove it from the expression

x^{2} = 24

Take the root of both sides of the equation and remember to use both positive and negative roots

x = \pm 24

Simplify the expression

More Steps

Evaluate

24

Write the expression as a product where the root of one of the factors can be evaluated

4 \times 6

Write the number in exponential form with the base of 2

2^{2} \times 6

The root of a product is equal to the product of the roots of each factor

2^{2} \times 6

Reduce the index of the radical and exponent with 2

26

x = \pm 26

Separate the equation into 2 possible cases

x = 26 x = - 26

Solution

x_{1} = - 26, x_{2} = 26

Alternative Form

x_{1} \approx - 4.898979, x_{2} \approx 4.898979
