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

Accepted Solution

A:

Answer:Discriminant = 88Step-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
