Question

Simplify (x^3+8x+5)-(2x^2-3x-12)

Answer 1

$\bold{Answer}$

$\boxed{\bold{x^3-2x^2+11x+17}}$

$\bold{Explanation}$

• $\bold{Solve: \ \left(x^3+8x+5\right)-\left(2x^2-3x-12\right)}$

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

• $\bold{Remove \ Parenthesis \ (a) \ = \ a}$

$\bold{x^3+8x+5-\left(2x^2-3x-12\right)}$

• $\bold{Simplify \ -\left(2x^2-3x-12\right): \ -2x^2+3x+12}$

$\bold{x^3+8x+5-2x^2+3x+12}$

• $\bold{Simplify \ x^3+8x+5-2x^2+3x+12: \ x^3-2x^2+11x+17}$

$\bold{x^3-2x^2+11x+17}$

$\boxed{\bold{Eclipsed}}$

Answer 2
