Question

What should be subtracted from 8x³ +3x²+9 to obtain 4x³-5x²+8x-4? ans in detail

Answer 1

Step-by-step explanation:

so we have to subtract something

let that be = y

8x^3 +3x^2 +9 -(y) = 4x^3-5x^2+8x-4

8x^3+3x^2+9 -(4x^3-5x^2+8x-4) = y

8x^3+3x^2+9-4x^3+5x^2-8x+4 = y

4x^3+8x^2+13-8x = y
