Solution 1

The given equation is -v^2 + 5v + 6 = -2v^2.

First, let's simplify this equation by adding 2v^2 to both sides to get rid of the negative sign on the right side. This gives us:

v^2 + 5v + 6 = 0

Now, we can use the quadratic formula to solve for v. The quadratic formula is:

v = [-b ± sqrt(b^2 - 4ac)] / (2a)

In this equation, a = 1, b = 5, and c = 6.

Substituting these values into the quadratic formula gives us:

v = [-5 ± sqrt((5)^2 - 416)] / (2*1) v = [-5 ± sqrt(25 - 24)] / 2 v = [-5 ± sqrt(1)] / 2

So, the solutions are:

v = [-5 + 1] / 2 = -2 v = [-5 - 1] / 2 = -3

Therefore, the solutions to the equation are v = -2 and v = -3.

Solution 2

The given equation is -v^2 + 5v + 6 = -2v^2.

First, let's simplify the equation by adding 2v^2 to both sides to get rid of the negative sign on the right side. This gives us:

v^2 + 5v + 6 = 0

This is a quadratic equation in the form of ax^2 + bx + c = 0, where a = 1, b = 5, and c = 6.

The quadratic formula is given by:

v = [-b ± sqrt(b^2 - 4ac)] / (2a)

Substituting the values of a, b, and c into the quadratic formula gives:

v = [-5 ± sqrt((5)^2 - 416)] / (2*1) v = [-5 ± sqrt(25 - 24)] / 2 v = [-5 ± sqrt(1)] / 2 v = [-5 ± 1] / 2

So the solutions are v = (-5 + 1)/2 = -2 and v = (-5 - 1)/2 = -3.
