Question

Use to Quadratic Equation to answer this a) what is the value of the discriminant $3x {}^{2} - 2x + 5 = 0$

Answer 1

Given:

$3x^2-2x+5=0$

To find the discriminant, use the discriminant formula in the quadratic equation below:

$D\text{ = }b^2-4ac$

Where,

a = 3

b = -2

c = 5

Input the values into the discriminant formula:

$\begin{gathered} D\text{ = (}-2)^2-4(3)(5) \\ \\ D\text{ = 4 - }60\text{ } \\ \\ D\text{ = -56} \end{gathered}$

Therefore, the value of the discriminant is -56

ANSWER:

-56
