Question

Solve x2 − 60 = 0. If necessary, round to the nearest hundredth.
±7.75
±120
3600
There is no solution as you cannot take the square root of a negative number.

Answer 1

Answer:

Option A, $x =$ ± $7.75$

Step-by-step explanation:

Step 1:  Add 60 to both sides

$x^2 - 60 = 0$

$x^2 - 60 + 60 = 0 + 60$

$x^2 = 60$

Step 2:  Square root both sides

$\sqrt{x^2} = \sqrt{60}$

$x =$ ± $7.75$

Answer:  Option A, $x =$ ± $7.75$
