Question

Difference in the following polynomials (6x^3 - 2x^2 + 4) -(2x^3 + 4x^2 - 5)

Answer 1

$\bold{[ \ Answer \ ]}$

$\boxed{\bold{4x^3-6x^2+9}}$

$\bold{[ \ Explanation \ ]}$

• $\bold{Find \ Difference: \ \left(6x^3\:-\:2x^2\:+\:4\right)-\left(2x^3\:+\:4x^2\:-\:5\right)}$

$\bold{-----------------------}$

• $\bold{Remove \ Parenthesis}$

$\bold{6x^3-2x^2+4-\left(2x^3+4x^2-5\right)}$

• $\bold{Remove \ Parenthesis \ / \ Simplify}$

$\bold{-\left(2x^3+4x^2-5\right): \ -2x^3-4x^2+5}$

• $\bold{Rewrite}$

$\bold{6x^3-2x^2+4-2x^3-4x^2+5}$

• $\bold{[Simplify \ 6x^3-2x^2+4-2x^3-4x^2+5] \ 4x^3-6x^2+9}$

$\bold{4x^3-6x^2+9}$

$\boxed{\bold{[] \ Eclipsed \ []}}$
