Based on the calculations, [tex]7x -9[/tex] subtracted from [tex]2x^2-11[/tex] is equal to [tex]2x^2-7x-2[/tex].
Given the following data:
In this exercise, you're required to subtract equation one (1) from equation two (2). This ultimately implies that, we would subtract (minus) one of the equations from the other to produce a new equation.
Mathematically, this is given by this expression:
[tex]2x^2-11-(7x-9)\\\\[/tex]
Opening the bracket, we have:
[tex]2x^2-11-7x+9\\\\2x^2-7x-11+9\\\\2x^2-7x-2[/tex]
Note: The resulting equation is a quadratic equation.
