Respuesta :

Answer:

Option c)

Step-by-step explanation:

Given quadratic equation is

[tex]-2x^2+3x+4=7[/tex]

[tex]-2x^2+3x+4-7=0[/tex]

[tex]-2x^2+3x-3=0[/tex]

Multiply the above equation into (-) we get,

[tex]2x^2-3x+3=0[/tex]

To find the solution of quadratic equation [tex]ax^2+bx+c=0[/tex] is

[tex]x=-b
