3x squared = 108, what is value of x?

Question

3x^2, show me how you worked it out

Answer 1

Solve for the "x" variable in the following equation...

3x^2 = 108

First: isolate x^2 on one side by dividing both sides by 3 (when you move a term to the opposite side, always use the opposite sign).

(3x^2)/3 = (108)/3

x^2 = 108/3

x^2 = 36

Sec: eliminate the exponent by finding the square root of both sides (V` represents a radical sign).

V`(x^2) = +/- V`(36)

V`(x^2 * x^2) = +/- V`(6*6)

x = +/- 6

x = 6 and - 6

Answer 2

If 3x^2 is 108, x^2 is 36 by dividing both sides by 3.

Then, the square root of 36 is 6. You can check it because 6^2 is 36. You either need to memorize common sqaures from 1 to about 15, and this will make your life much much easier. Unless you want to type it in the calculator every time.

Answer 3

3 x^2 = 108

x^2 = 108/3

x^2 = 36

x = 6 or x = -6

Answer 4

3x squared = 108

x squared = 108/3 = 36

x = square root of 36

x = 6.

Answer 5

The goal is to get x by itself.

3x^2=108.

The first thing you want to do is divide both sides by 3.

x^2=36

Then take the square root of each side

x=SQ36

The square root of 36 is 6

so x=6!

Answer 6

3x squared = 108 => x squared = 108/3 => x squared=36 => x= -6 or x=6. so the value of x is {-6,6}

Answer 7

First you may could be attentive to that the sum of the interior angles of a quadrilateral is 360. You subtract the 108, leaving you with 252 stages left to fill. You upload the three variables, getting 9x, because of the fact the -eight, +23, and -15 cancel out. as a effect, you have 9x=252. You divide 252 by 9 and get x=28. once you have different issues like this, you only remember what proportion stages could be interior, and paintings it out from there like this.

Answer 8

3x^2=108
x=108 divided by 3
x^2=36
root of x =6
therefore x =6

Answer 9

3x^2=108

Divide both sides by 3
3x^2/3=108/3
x^2=36
sqrt of x^2=sqrt of 36
x=6

Answer 10

3x^2 = 108
(3x^2)/3 = 108/3
x^2 = 36
sqrt (x^2) = sqrt (36)
x = 6
