simplify (x+4)(x^2-4x+16)+(5-x)(25+5x+x^2)

simplify

(x + 4) (x^{2} - 4 x + 16) + (5 - x) (25 + 5 x + x^{2})

189

Solution steps

(x + 4) (x^{2} - 4 x + 16) + (5 - x) (25 + 5 x + x^{2})

Expand

(x + 4) (x^{2} - 4 x + 16) : x^{3} + 64

= x^{3} + 64 + (5 - x) (25 + 5 x + x^{2})

Expand

(5 - x) (25 + 5 x + x^{2}) : - x^{3} + 125

= x^{3} + 64 - x^{3} + 125

Group like terms

= x^{3} - x^{3} + 64 + 125

Add similar elements:

x^{3} - x^{3} = 0

= 64 + 125

64 + 125 = 189

= 189
