Question

what is value of the discriminant of f
f(x)=3x²+24x+48​

Answer 1

Respuesta:

To find the discriminant we have to evaluate the variables of the quadratic equation

Explicación paso a paso:

In the quadratic formula, the expression under the sign of the square root, b 2 - 4 ac, is called the discriminant e. If the discriminant b 2 - 4 ac is negative, then there are no real solutions to the equation. (You need complex numbers to handle this case properly.

f(x)=3x²+24x+48

f(x) = ax² + bx + c

 Δ = b² - 4 a c

a = 3

b = 24

c = 48

 Δ = ( 24 )² - 4 ( 3 ) ( 48 )

Δ = 0

the discriminant is 0 therefore its solutions, intersections or roots are only one, since the parabola is tangent to the abscissa axis
