Question

find
the
discriminant x^2-3x - 10-0.​

Answer 1

Answer:

I assume the equation is x² - 3x - 10 = 0

Discriminant = b² - 4ac

a = 1, b = -3, c = -10

D = (-3)² - 4(1)(-10)

D = 9 + 40

D = 49

Answer 2

on comparing this eq with standard form of quadratic equation ax²+bx+c =0

we get

a= 1 , b= -3 and c= -10

D= b²-4ac = -3² -4×1 ×-10 = 9+40 = 49
