Step-by-step explanation:

\tt{2 {x}^{2}  + 5x - 3 = 0}

⇢ \sf{2 {x}^{2}  + 5x  + ( -  3) = 0}

Here , a = 2 , b = 5 & c = -3 {a is the coefficient of x² , b is the coefficient of x and c is the constant term }

Now ,

\tt{x =  \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} }

⇢ \tt{x =  \frac{ - 5± \sqrt{ {5}^{2} - 4 \times 2 \times ( - 3) } }{2 \times 2} }

⇢ \sf{ x=  \frac{ - 5±7}{4} }

Taking positive ( + ) sign :

⇝\tt{x =  \frac{ - 5 + 7}{4}  =  \frac{1}{2}}

Taking negative ( - ) sign :

⇝\tt{x =  \frac{ - 5 - 7}{4}  =  - 3}

\purple{ \boxed{ \boxed{ \tt{⤑ \: Our \: final \: answer  :  \boxed{ \underline{ \tt{x =  \frac{1}{2} , \:  - 3}}}}}}}

Hope I helped ! ツ

Have a wonderful day / night♡
