How many solutions would a quadratic equation have if the discriminant is 12? brainliest to the first correct answer

two

Step-by-step explanation:

If the discriminant of a quadratic equation is 12 then it has two distinct real roots. That 12 is not a perfect square, so if the coefficients of the quadratic are integers or otherwise rational, then the roots are both irrational.

a

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
