Question

subtract the sum of -3x³ y² + 2x² and - 3x² y³ - 5y4 from x4 + x³ y² + x² y³ + y4​

Answer 1

Answer:

x4+ 4x³ y²+  4x² y³+ 6y4 -2x²

Step-by-step explanation:

Sum of (-3x³y²+2x²)  and  (-3x²y³-5y4)

= (-3x³y²+2x²) + (-3x²y³-5y4)

= -3x³y²+2x²-3x²y³-5y4

subtract this answer from x4 + x³ y² + x² y³ + y4

= x4 + x³ y² + x² y³ + y4 - (-3x³y²+2x²-3x²y³-5y4)

= x4 + x³ y² + x² y³ + y4 +3x³y²-2x²+3x²y³+5y4

= x4+ 4x³ y²+  4x² y³+ 6y4 -2x²
