What are the values of a, b, and c in the quadratic equation 0 = 5x – 4x2 – 2?

a = 5, b = 4, c = 2
a = 5, b = –4, c = –2
a = –4, b = 5, c = –2
a = 4, b = –5, c = –2

Question

What are the values of a, b, and c in the quadratic equation 0 = 5x – 4x2 – 2?

a = 5, b = 4, c = 2
a = 5, b = –4, c = –2
a = –4, b = 5, c = –2
a = 4, b = –5, c = –2

ax^2+bx+c=0
Compare with this equation

mathstudent55 · Answer

The standard form of a quadratic equation is

$\large ax^2 + bx + c\ = 0$

Rewrite your equation in this form and compare the coefficients.

mathstudent55 · Answer

$\large 0 = \color{red}{5}x \color{blue}{- 4}x^2 \color{green}{- 2}$

$\large \color{blue}{- 4}x^2 + \color{red}{5}x +\color{green}{(- 2)} = 0$

$\large \color{blue}{a}x^2 + \color{red}{b}x + \color{green}{c} = 0$
