Answer:
b = 5
Step-by-step explanation:
All quadratic equations are formed in the format of [tex]a^{2}[/tex] + bx + c = 0
Using this formula, we can re-arrange the equation to fit the given format.
[tex]3x^{2}[/tex] - 2 = -5x
[tex]3x^{2}[/tex] + 5x - 2 = 0
5 is plugged in for "b" in this equation, therefore b = 5.
