hoblos · Answer

b2 - 4ac
for 2x2 + 7x + 3 = 0
b2 - 4ac= 7^2 - 4*3*2 = 25

Discriminant  tells us if a quadratic equation can be solved or not.
$$D=b^2-4ac$$
option b

radar · Answer

$$b ^{2}-4ac$$
is termed the discriminant and if that value:
is positive the equation has two real solutions
is 0 the equation has one (repeated) solution
is negative the equation has no real solutions (solutions are complex numbers)
