What are the solutions of the quadratic equation below? 3x2 - x = 11

A quadratic equation         ....[1]

then the solution is given by:

Given the equation:

Subtract 11 from both sides we have;

On comparing with [1] we have;

a = 3 , b  =-1 and c =-11

Substitute these we have;

⇒

⇒

Therefore, the solution for the given equations are:

,

where is the option given

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
