Question

Solve the equation using square roots.

Answer 1

Answer: LAST OPTION.

Step-by-step explanation:

1. You have the following equation:

$6x^{2}=54$

2. Then you must solve for x, as following:

$x^{2}=54/6\\x^{2}=9\\x=\sqrt{9}\\x=+/-3$

Therefore, as you can see above, the answer for the exercise is the last option.

Answer 2

Answer:

Choice d is correct.

Step-by-step explanation:

we have given equation

6x²=54

we have to solve this equation by using square roots.

for this, divide the above equation by 6 from both sides.

after applying division the equation become

6x²/6 = 54/6

x² = 9

now applying square root on both sides.

√x² = √9

so the final equation become:

x = ± 9

x = ± 9 is the required answer.
