Question

X-x^(2)-1=3x^(2)-8x+1​

Answer 1

вроде так, если я не ошибаюсь

Answer 2

It looks like you have a quadratic equation that you would like to solve for the variable x. The given equation is:

X - x^2 - 1 = 3x^2 - 8x + 1

To solve this equation, we'll first move all terms to one side of the equation to set it equal to zero:

x^2 + 3x^2 - x + 8x + 1 + 1 - X = 0

Combine like terms:

4x^2 + 7x + 2 - X = 0

Now, we have a quadratic equation in standard form:

4x^2 + 7x + 2 - X = 0

To solve this quadratic equation, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

In this case, the coefficients are:

a = 4 b = 7 c = 2 - X

Plugging these values into the formula:

x = (-(7) ± √((7)^2 - 4(4)(2 - X))) / (2(4))

Simplify the expression under the square root:

x = (-7 ± √(49 - 32 + 4X)) / 8

x = (-7 ± √(17 + 4X)) / 8

So, the solutions for the equation are:

x = (-7 + √(17 + 4X)) / 8 x = (-7 - √(17 + 4X)) / 8

These are the solutions for the given equation.
