Question

3х²+(х-2)(-3х+1)=-23​

Answer 1

………ответ будет х= -3

Answer 2

To solve the equation 3x² + (x - 2)(-3x + 1) = -23, we'll begin by expanding the expression on the left side and simplifying the equation.

Expanding the equation: 3x² + (x - 2)(-3x + 1) = -23 3x² + (-3x² + x + 6x - 2) = -23 3x² - 3x² + x + 6x - 2 = -23 x + 7x - 2 = -23 8x - 2 = -23

Now, let's isolate the variable x by moving the constants to the other side of the equation:

8x - 2 = -23 8x = -23 + 2 8x = -21

To solve for x, we'll divide both sides of the equation by 8:

8x/8 = -21/8 x = -21/8

Therefore, the solution to the equation 3x² + (x - 2)(-3x + 1) = -23 is x = -21/8.
