Step-by-step explanation:
Hey there!!!
1. Ans.
The formula for quadratic equation,
[tex]x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a} [/tex]
2. Ans.
When, the quadratic equation is given, in the form of;
[tex]a {x}^{2} + bx + c = 0[/tex]
Then, "a" is the coefficient of x "b" is the coefficient of y. and c is the constant value.
3.Ans.
[tex] \sqrt{ {b}^{2} - 4ac } \: tells \: us \: the \: type \: of \: solutions.[/tex]
Hope it helps..
