Answer:
D=41
Explanation:
4x² + 3x − 2 = 0
To find the discriminant we need to use formula
D = b² - 4 ac
Quadratic equation in general form:
ax² + bx + c = 0
4x² + 3x − 2 = 0
We can see that
a = 4, b = 3 , c = -2
So, D = 3² - 4*4*(-2) = 9 +32 = 41
D = 41 is positive , so given equation has 2 real solutions.
If D = 0 , there is 1 real solution.
If D< 0 , then there is no real solutions.
