simplify (x^2+3x-4)+(2x^3-2x+5)

simplify

(x^{2} + 3 x - 4) + (2 x^{3} - 2 x + 5)

2 x^{3} + x^{2} + x + 1

Solution steps

(x^{2} + 3 x - 4) + (2 x^{3} - 2 x + 5)

Simplify

(x^{2} + 3 x - 4) + (2 x^{3} - 2 x + 5) : x^{2} + 3 x - 4 + 2 x^{3} - 2 x + 5

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

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

Add similar elements:

3 x - 2 x = x

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

Add the numbers:

- 4 + 5 = 1

= 2 x^{3} + x^{2} + x + 1

(\frac{2 ^{2}}{x})^{- 1}

\frac{2}{4} \cdot \frac{3}{6}

(- 10 x + 10) - (- 4 x + 4)

(x - 5)^{2} + 1

(3 x + 5) (2 x + 3)
