Question

Find the value of the discriminant of the quadratic equation : 2x^2 + 3 + x =0

Answer 1

Answer:

$2x {}^{2} + 3 + x = 0 \\ a = 2 \\ b = 3 \\ c = 1 \\ now \\ we \: have \\ \\ discriminant = b {}^{2} - 4ac \\ = 3 { }^{2} - 4 \times 2 \times 1 \\ = 9 - 8 \\ = 1 \\ therefore \: th \: value \: of \: discriminant \: is \: 1$
