Heyy Buddy

Here's your Answer

Quadratic Formula :-

a {x}^{2}  + bx + c = 0

Here,

a = 2 , b= 1 and c = 3.

d =  \frac{ - b  +  \sqrt{ {b}^{2}  - 4ac}  }{2a}  \\  \\  =  >   \frac{ -1 +  \sqrt{ {1}^{2}  - 4 \times 2 \times 3} }{2 \times 2} \\  \\  =  >  \frac{ - 1 +  \sqrt{1 - 24}  }{4}  \\  \\  =  >  \frac{ - 1 +  \sqrt{ - 23} }{4}  \\  \\  =  >  \frac{ - 1 +  \sqrt{23} }{4}
