What is 3X^2-7=11
It is an equation.
Are you supposed to find the value of X?
If so, try starting with
3X^2 -18 = 0
which is equivalent to saying
X^2 - 6 = 0
Try factoring it, to get the value of X.
3X^2-7=11
3x^2 = 18
x^2 = 6
x = ± √6
To solve the equation 3X^2 - 7 = 11, we'll need to isolate the variable X. Here's how you can do it step by step:
1. Start by moving the constant term (-7) to the right side of the equation by adding 7 to both sides:
3X^2 - 7 + 7 = 11 + 7
This simplifies to:
3X^2 = 18
2. Next, divide both sides of the equation by the coefficient of X^2, which is 3:
(3X^2)/3 = 18/3
This simplifies to:
X^2 = 6
3. To solve for X, we need to take the square root of both sides of the equation. However, keep in mind that taking the square root introduces a positive and negative solution:
√(X^2) = √6
X = ±√6
So the solutions to the equation 3X^2 - 7 = 11 are X = √6 and X = -√6.
