Answer:

x = 3 \:  \: or \:  -  \frac{1}{2}

Step-by-step explanation:

2 {x}^{2}  - 5x - 3 = 0 \\ 2 {x}^{2}  - 6x + x - 3 = 0 \\ 2x(x - 3) + 1(x  - 3) = 0 \\ (2x + 1)(x - 3) = 0 \\ 2x + 1 = 0 \:  \: or \:  \: x - 3 = 0 \\ x =  -  \frac{1}{2}  \:  \: or \:  \: x = 3

Hope it helps you.

Answer:

Here's your answer friend.

Step-by-step explanation:

First-

Write -5x as a difference

2x {}^{2}  + x - 6x - 3 = 0

factor out x from the expression

x(2x + 1) - 6x - 3 = 0

factor out -3 from the expression

x(2x - 1) - 3(2x - 1) = 0

separate into possible cases

(2x + 1)(x - 3)

this equation has two solutions

x =  \frac{ - 1}{2}  \\ x = 3

thanks

that's your answer friend.
