What is the value of the discriminant for the quadratic equation
2a2+ 7a + 3 = 0?
Please Help!
Which value of x makes the equation 1.25(4 x -10) = 7.5 true?
To find the value of the discriminant for a quadratic equation ax^2 + bx + c = 0, you can use the formula:
Discriminant = b^2 - 4ac
In this case, the quadratic equation is 2a^2 + 7a + 3 = 0.
First, identify the values of a, b, and c:
a = 2
b = 7
c = 3
Now, substitute these values into the formula for the discriminant:
Discriminant = (7)^2 - 4(2)(3)
Simplifying this expression, we get:
Discriminant = 49 - 24
Calculating further, we have:
Discriminant = 25
Therefore, the value of the discriminant for the given quadratic equation is 25.
