The General Form of the Quadratic Multiple Regression Models Is $\beta$

The general form of the quadratic multiple regression models is:

A) y = $\beta$ ₁X₁+ $\beta$
₂X₂+ $\varepsilon$
B) y = $\beta$ ₀+ $\beta$
₁X₁+ $\beta$
₂X₂+ $\varepsilon$
C) y = $\beta$ ₀+ $\beta$
₁X + $\beta$
₂X²+ $\varepsilon$
D) y = $\beta$ ₀+ $\beta$
₁X²+ $\varepsilon$
E) y = $\beta$ ₀+ $\beta$
₁X₁+ $\beta$
₂X₂²+ $\varepsilon$
