Answer:

x=-1

Step-by-step explanation:

\(3x^{2}-2x-5=0\)\(a=\textcolor{#B14BA5}{3}\)\(b=\textcolor{#D24040}{-2}\)\(c=\textcolor{#3172E0}{-5}\)\(x=\frac{-(\textcolor{#D24040}{-2})\pm \sqrt{(\textcolor{#D24040}{-2})^{2}-4\cdot \textcolor{#B14BA5}{3}(\textcolor{#3172E0}{-5})}}{2\cdot \textcolor{#B14BA5}{3}}\)

Answer:

x = -1 and x = 5/3

Step-by-step explanation:

3x2 - 2x - 5 = 0

By Factorization,

3x2 + 3x -5x - 5 = 0

3x(x + 1) -5(x + 1) = 0

(x + 1)(3x - 5) = 0

x + 1 = 0 and 3x - 5 = 0

x = -1 and 3x = 5

x = -1 and x = 5/3
