Select TWO possible values for x in the equation x2=45.
kirill [66]

Answer:

3 \sqrt 5}  and -3 \sqrt 5}

Step-by-step explanation:

Given

x^2 = 45

Required

Determine the values of x

x^2 = 45

Take square root of both sides

\sqrt{x^2} = \±\sqrt{45}

x = \±\sqrt{45}

Expand 45 as 9 * 5

x = \±\sqrt{9 * 5}

Split the square root

x = \±(\sqrt{9} *\sqrt 5}

x = \±3 *\sqrt 5}

x = \±3 \sqrt 5}

This can be further split to:

x = 3 \sqrt 5} or x = -3 \sqrt 5}

Hence, the possible values of x are

3 \sqrt 5}  and -3 \sqrt 5}
