Question

Use any method to solve the equation. If necessary, round to the nearest hundredth. 9x^2 = 17

Answer 1

Answer:

1.37

Step-by-step explanation:

First, we want to isolate the variable x. Do this by dividing both sides by 9:

$\frac{9x^2}{9} =17/9$

$x^{2} =17/9$

Now, square root both sides:

$\sqrt{x^2}= \sqrt{17/9}$

x = $\sqrt{17/9} =\sqrt{17}/3$

Finally, we can use a calculator to finish off the problem:

x = $\sqrt{17}/3$ ≈ 1.37

Hope this helps!

Answer 2

9x^2 = 17

Divide both sides by 9

X^2 = 17/9

Take the square root of both sides

X = sqrt(17/9) and -sqrt(17/9)

Simplify:

X = sqrt(17)/3 and -sqrt(17)/3
