Question

F(x) = (3x-5)(4x+2)
is the function linear or quadratic ?

Answer 1

f(x)=(3x-5)(4x+2) is a quardatic function.

Explanation:

f(x)=(3x-5)(4x+2)

simplify

f(x)=3x(4x+2)-5(4x+2)

f(x)=
`12x^(2) +6x-20x-10`

adding the coefficients of x, we get

f(x)=
`12x^(2) -14x-10`

which is quardatic equation since it contains the terms 12
`x^(2)`.
