Question

Determine whether the function is linear or quadratic. Identify the quadratic, linear, and constant terms of the equation: y=(x-1)(4x+2)-4x^2

Answer 1

Hello,

Multiplying (x-1) by (4x+2) the term in x² is x*4x=4x².
If we substract 4x² the term of y in x² will be 0.
The function is not quadratic.

Since 4x*(-1)+2*x=-2x (product of terms in x) : the function is thus linear.

Constant term is -1*2=-2
