Question

3x^2=96

Answer 1

Solution for 3x^2=96

Simplifying
3x2 = 96

Solving
3x2 = 96

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '3'.
x2 = 32

Simplifying
x2 = 32

Take the square root of each side:
x = {-5.656854249, 5.656854249}

Answer 2

I did that & i got an answer around 400 when i plugged the value in for x and tried to solve for the equation.

Answer 3

okay since you did that, Whatever answer you got is correct

Answer 4

No because i need 3x^2 to equal to 96. If I use 5.657 and plug that in for x, b(5.657)^2, its not gonna equal to 96.

Answer 5

Not recommended. ALWAYS factor.

3x^2=96

x^2 = 32
x^2 - 32 = 0
(x+sqrt(32))(x-sqrt(32)) = 0

x = sqrt(32) or x = -sqrt(32)

Note: Never say, use, or perform anything that is called "plug in".

Answer 6

why is it never factored? does that go for (3+x)^2 as well?
