What is the discriminant of the polynomial below 2x^2+4x-9

Discriminant = 88

Step-by-step explanation:

The general form of quadratic polynomial is:

P(x) = ax² + bx + c ⇒ a is the coefficient of x² , b is the coefficient

of x and c is the numerical term

∵ The discriminant of P(x) = ax² + bx + c is b² - 4ac

∵ P(x) = 2x² + 4x - 9

∴ a = 2 , b = 4 , c = -9

∴ Discriminant = (4)² - 4(2)(-9) = 16 + 72 = 88
