To find the possible values of n in the quadratic equation 2n² + 7n + 6 = 0, we can use the quadratic formula:
n = (-b ± √(b² – 4ac)) / 2a
In this equation, a is the coefficient of n² (which is 2), b is the coefficient of n (which is 7), and c is the constant term (which is 6).
First, we need to calculate the discriminant:
b² – 4ac = 7² – 4(2)(6)
b² – 4ac = 49 – 48 = 1
Now that we have the discriminant, we can substitute a, b, and the discriminant into the quadratic formula:
n = (-7 ± √1) / (2 * 2)
This simplifies to:
n = (-7 ± 1) / 4
Next, we solve for the two possible values of n:
- n = (-7 + 1) / 4 = -6 / 4 = -3/2
- n = (-7 – 1) / 4 = -8 / 4 = -2
Therefore, the possible values of n in the quadratic equation 2n² + 7n + 6 = 0 are:
- n = -3/2
- n = -2
These values can be interpreted as the points where the parabola represented by the quadratic equation intersects the n-axis.
