Question

Given the functions j(x) = 3x2 − 2x + 5 and k(x) = 3x2 + 4, which operation results in a 1st degree polynomial?

Answer 1

subtraction. x2 trem gets cancelled leaving a 1 degree polynomial

Answer 2

Subtracting both the equations.

Explanation:

The given functions are:

`j(x)=3x^2-2x+5` and

`k(x)=3x^2+4`

The given functions are two degree polynomials, thus in order to make them a one degree polynomial, we must subtract both the equations,

therefore,
`j(x)-k(x)=3x^2-2x+5-3x^2-4`

⇒
`j(x)-k(x)=-2x+1`

which results in first degree polynomial.
