Type your math problem... (1-x) ^2 - 9= 0

Question

Solve the quadratic equation

Solve using square roots

Solve by factoring

Solve using the quadratic formula

x_{1} = - 2, x_{2} = 4

Evaluate

(1 - x)^{2} - 9 = 0

Add or subtract both sides

(1 - x)^{2} = 9

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

1 - x = \pm 9

Simplify the expression

1 - x = \pm 3

Separate the equation into 2 possible cases

1 - x = 3 1 - x = - 3

Solve the equation

More Steps

Evaluate

1 - x = 3

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

- x = 3 - 1

Subtract the numbers

- x = 2

Change the signs on both sides of the equation

x = - 2

x = - 2 1 - x = - 3

Solve the equation

More Steps

Evaluate

1 - x = - 3

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

- x = - 3 - 1

Subtract the numbers

- x = - 4

Change the signs on both sides of the equation

x = 4

x = - 2 x = 4

Solution

x_{1} = - 2, x_{2} = 4
