Hey can you please help me posted picture of question

Answer 1

Hey there :)

( 8x⁸ + 8x⁷ + 9 ) - ( 3x⁷ + 2x + 5 )

Distribute the " - " sign into the brackets to get rid of them

8x⁸ + 8x⁷ + 9 - 3x⁷ - 2x - 5

Combine any like terms
8x⁸ + 8x⁷ - 3x⁷ - 2x + 9 - 5
8x⁸ + 5x⁷ - 2x + 4


`\boxed {Your \ answer \ will \ be \ Option \ B }`

Answer 2

The step by step solution is listed below.


`8x^(8)+8x^(7)+9-(3x^(7) +2x+5) \\ \\ =8 x^(8) +8 x^(7)+9-3 x^(7)-2x-5 \\ \\ =8 x^(8)+5 x^(7)-2x+4`

Thus, the correct answer to this question is Option B
