What is the discriminant for the quadratic expression? 24x2 + 13x A. 73 B. 524 C. 265 D. 169

The discriminant is the bit in the quaratic equaiton under the squaer root sign

that is b^2-4ac

3 cases

if

b^2-4ac>0, there are 2 real roots

b^2-4ac=0, there is 1 real root

b^2-4ac<0, there are 2 imaginary roots

ax^b+bx+c=0

24x^2+13x

a=24

b=13

13^2-4 (24)

169-96

73

discriminatn is 73 A
