Question
Use the quadratic formula to solve. Express your answer in simplest form.minus, v, squared, plus, 5, v, plus, 6, equals, minus, 2, v, squared−v 2 +5v+6=−2v 2
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.
