Question

Classify the following as Linear or Quadratic. Then identify the quadratic, linear, and constant terms.

x + 2x(x-3)

Answer 1

quadratic, 2, -5, 0

Explanation:

x + 2x(x-3)

= x + 2x^2 - 6x

= 2x^2 - 5x

so the eqn is quadratic

the quadratic term is 2,

the linear term is -5, and

the constatnt term is 0

Answer 2

This is quadratic since it has an x^2

The quadratic term is 2x^2, the linear term is -5x and the constant term is 0

Explanation:

x + 2x(x-3)

Distribute the 2x

x + 2x^2 -6x

Combine like terms

2x^2 -5x

This is quadratic since it has an x^2

The quadratic term is 2x^2, the linear term is -5x and the constant term is 0
