Which of the quadratic functions listed is written in standard form? O A. v= (x + 1)(x - 5) O B.V -- 7 = -2(x+3)2 c. V-4 = - 3(x - 5) O d. v= 2x2 + 3.1 - 5

The standard form of a quadratic equation is
[tex]y=ax^2+bx+c[/tex]Where a, b and c are constants
The standard form of a quadratic equation in the given question is
[tex]y=2x^2+3x-5[/tex]Hence, the right option is D
