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
