pls help me with this​

Answer 1

Answer:

1.5x⁴-3x²+4+(6x³-4x²-7)

5x⁴-3x²+4+6x³-4x²-7

5x⁴+6x³-7x²-3

2.(-7x³y+4x²y²-2)+(4x³y+1-8x²y²)

-7x³y+4x²y²-2+4x³y+1-8x²y²

-7x³y+4x³y+4x²y²-8x²y²-2+1

-3x³y-4x²y²-1

3.(5+24y³-7y²)+(-6y³+7y²+5)

5+24y³-7y²-6y³+7y²+5

18y³+0+10

18y³+10

4.(2x⁵-6x³-12x²-4)+(-11x⁵+8x+12x²+6)

2x⁵-11x⁵-6x³-12x²+12x²+6-4

-9x⁵-6x³+0+2

-9x⁵-6x³+2

5.(3y⁵-2y+y⁴+2y³+5)+(2y⁵+3ý³+y+4)

3y⁵+2y⁵+y⁴+3y³+2y³+y-2y+5+4

5y⁵+y⁴+5y³-y+9
