Apabila x = p^(2) − p^(q) + 3^(q)^(2) dan y = p^(2) − 2(p^q) − (q^2) maka: e) −4x + (−2x) + y =

Apabila x = p^(2) − p^(q) + 3^(q)^(2) dan y = p^(2) − 2(p^q) − (q^2) maka: e) −4x + (−2x) + y =

Jawabannya adalah – 5p² – 8p^q+17q²

−4x + (−2x) + y
= – 6x +y
= – 6p²-6p^q+18q²+p²-2p^q-q²
= – 5p² – 8p^q+17q²
