Por Favor! Alguém me ajuda. Calcule o quadro da diferença de dois termos: (3a-b)²: A)9a²-6ab+b² B)9a²+6ab-b² C)-9a²+6ab+b² D)-9a²-6ab-b² E)9a²+6ab+b²

Convert the cartesian equation (x 2 + y 2)2 = 4(x 2 - y 2) to a polar equation. choices: r4 = -4r2 r2 = 4cos2θ r2 = 4sin2θ

Match the equivalent expressions. x - 3y + 12 12 - 3y - 2x + x + 2x 3x + 2y - 2x + y + 12 3y + 12 3x + y - 12 4y + 3y + 3x - 6y - 10 - 2 x + 3y + 2x - 3x + 7 + 5 x + 3y + 12 5 + 2y + 7x - 4x + 3y - 17
