Question

subtract:
2x^4-7x^2+5x+3 from x^4-3x^3-2x^2+3​

Answer 1

Answer:

x^4 - 3x^3 + 5x^2 - 5x

Step-by-step explanation:

Substracting ( 2x^4 - 7x^2 + 5x + 3) from ( x^4-3x^3-2x^2+3 )

= ( x^4-3x^3-2x^2+3 ) -  ( 2x^4 - 7x^2 + 5x + 3)

= x^4-3x^3-2x^2+3-2x^4 + 7x^2 - 5x - 3

= ( x^4 - 2x^4 ) + ( -3x^3) + (-2x^2 + 7x^2) - 5x + 0

= x^4 - 3x^3 + 5x^2 - 5x
