Type your math problem... 100-x^2

Question

Factor the expression

(10 - x) (10 + x)

Evaluate

100 - x^{2}

Rewrite the expression in exponential form

1 0^{2} - x^{2}

Solution

(10 - x) (10 + x)

Show Solution

x_{1} = - 10, x_{2} = 10

Evaluate

100 - x^{2}

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

100 - x^{2} = 0

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

- x^{2} = 0 - 100

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

- x^{2} = - 100

Change the signs on both sides of the equation

x^{2} = 100

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

x = \pm 100
