Quotien of 6x^4-15x^3-2x^2-10x-4÷3x^2+2
Pachacha [2.7K]

Answer: (6x^4 - 15x^3 - 2x^2 - 10x - 4) ÷ (3x^2 + 2)

= (6x^4 - 15x^3 + 4x^2 - 6x^2 - 10x - 4) ÷ (3x^2 + 2)

= (6x^4 + 4x^2 - 15x^3  - 10x - 6x^2 - 4) ÷ (3x^2 + 2)

= 2x^2(3x^2 + 2) - 5x(3x^2 + 2) - 2(3x^2 + 2) ÷ (3x^2 + 2)

= (3x^2 + 2)(2x^2 - 5x - 2) ÷ (3x^2 + 2)

= 2x^2 - 5x - 2               Ans.

I hope this helped!!! NO HATE COMMENTS IF I WAS WRONG!!!
