Drag and drop the expressions into the boxes to correctly complete the proof of the polynomial identity. (x2 + y2)² + 2x2y2 – y+ = x(x2 + 4y?)
(x2 + y) + 2xy - y = x2 (x2 + 4y2)
+2x²y2 – y4 = x(x2 + 4y2)
= x2 (x2 + 4y2)
x² (x² + 4x²)
x + 2x²y²
x² (x² + 47²) x² – 2x²y² + 3 x4 + 3 x + + 4x²y?
x4 + 2x2y2 + y4
