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

simplify

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

2 x^{3} - 15 x^{2} + 75 x - 120

Solution steps

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

Apply rule:

a + (b + c) = a + b + c

(x - 5)^{3} + (5 + x^{3}) = (x - 5)^{3} + 5 + x^{3}

= (x - 5)^{3} + 5 + x^{3}

Expand

(x - 5)^{3} : x^{3} - 15 x^{2} + 75 x - 125

= x^{3} - 15 x^{2} + 75 x - 125 + 5 + x^{3}

Group like terms

= x^{3} + x^{3} - 15 x^{2} + 75 x - 125 + 5

Add similar elements:

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

= 2 x^{3} - 15 x^{2} + 75 x - 125 + 5
