Question

(3x3+4x2)-(2x3+3x2-x)

Answer 1

Answer:

x^3 + x^2 + x

Step-by-step explanation:

3x^3 + 4x^2 − (2x^3 + 3x^2 − x)

Distribute the Negative Sign:

=3x^3 + 4x^2 + −1 (2x^3 + 3x^2 − x)

=3x^3 + 4x^2 + −1 (2x^3) + −1(3x^2) + −1 (−x)

=3x^3 + 4x^2 + −2x^3 + −3x^2 + x

Combine Like Terms:

=3x^3 + 4x^2 + −2x^3 + −3x^2 + x

=(3x^3 + −2x^3) + (4x^2 + −3x^2) + (x)

=x^3 + x^2 + x

Answer 2

Answer:

x^3 +x^2 +x

Step-by-step explanation:

(3x^3+4x^2)-(2x^3+3x^2-x)

Distribute the minus sign

(3x^3+4x^2)-2x^3-3x^2+x

Aline the like terms

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

x^3 +x^2 +x
