this the answer bro

Answer 2

Answer:

(7x⁴-2x³+x+10) + (3x⁴+15x³+9x²-8x+2) = 10x⁴ + 13x³ + 9x² -7x + 12

Step-by-step explanation:

7x⁴-2x³+x+10

3x⁴+15x³+9x²-8x+2

(7x⁴-2x³+x+10) + (3x⁴+15x³+9x²-8x+2)

= 7x⁴ + 3x⁴  + 15x³ -2x³ + 9x²  + x - -8x + 10 + 2

= 10x⁴ + 13x³ + 9x² -7x + 12

(7x⁴-2x³+x+10) + (3x⁴+15x³+9x²-8x+2) = 10x⁴ + 13x³ + 9x² -7x + 12
