Question

Ok I have this math problem: 3x^2=4^2+x^2 Can you help me solve for x and show me the steps?

Answer 1

\[3x^2 = 4^2 + x^ 2\]

Answer 2

right? ok, so there is an x term on either side, luckily they are both the same operation on x

Answer 3

you should move the x terms to one side, try the getting all the x terms on the left side

Answer 4

ok if i did that then it would take the [x^2\] from the 3

Answer 5

right, so the left side would be 2x^2 = 4^2....

Answer 6

2x^2 = 4*4 = 2*2*2*2, divide both sides by 2 => x^2 = 2*2*2 => solve for x...

Answer 7

\[3 x ^{2} = 4^{2}+x^{2} \rightarrow 2x^{2} = 4^{2}\]
Then \[ 4^{2}= 16 \rightarrow x^{2} = 8 \right arrow x = \pm 2 \sqrt{2} \]

Answer 8

[\4^{2} = 16 \rightarrow x^{2} = 8 \rightarrow x = +\] or \[- 2 \sqrt{2}\]
