f(x)=4x^2-17x + 3What is the value the discriminant F?How many distinct real numbers zeros does F have?

Sagot :

Answer:

• D=249

,

• Two real numbers zeros

Explanation:

Given the quadratic function:

[tex]f\mleft(x\mright)=4x^2-17x+3[/tex]

a=4, b=-17, c=3

The discriminant is obtained using the formula:

[tex]\begin{gathered} D=b^2-4ac \\ =(-17)^2-4(4)(3) \\ =289-48 \\ =249 \end{gathered}[/tex]

Since the discriminant is greater than 0, the equation has 2 real solutions (or zeros).

Note:

• If D<0, the equation has 0 real solutions.

,

• If D=0, the equation has 1 real solution.
