Question

Given the trinomial 3x2 - 6x + 5, what is the value of the discriminant?

Answer 1

please help the choices are -66, -24, 8, and 96

Answer 2

\(\bf ax^2+bx+c\qquad discriminant\implies b^2-4ac\\ \quad \\
3x^2 - 6x + 5\implies \textit{what do you think?}\)

Answer 3

huh??

Answer 4

a, b, and c, are just the coefficients, notice yours

Answer 5

im so confused

Answer 6

\(\bf \Large {\color{blue}{a}x^2\color{red}{+b}x+\color{green}{c}
\qquad discriminant\implies
\color{red}{b}^2-4\color{blue}{a}\color{green}{c}\\ \quad \\
\color{blue}{3}x^2 \color{red}{- 6}x \color{green}{+ 5}
\implies \textit{what do you think?}}\)

see it now?
