expand (x-5)(x-i)(x+i)

Solution

expand

(x - 5) (x - i) (x + i)

Solution

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

Solution steps

(x - 5) (x - i) (x + i)

Expand

(x - 5) (x - i) (x + i) : (x - 5) (x^{2} + 1)

= (x - 5) (x^{2} + 1)

Apply FOIL method

(x - 5) (x^{2} + 1) : x^{3} + x - 5 x^{2} - 5

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

Popular Examples

\frac{1}{x ( x ^{3} - 1 )}

expand (x-1)(2+sqrt(x+3))expand

(x - 1) (2 + x + 3)

simplify 4(sqrt(2)-1)simplify

4 (2 - 1)

expand ((x^3)/4-1/(x^3))^2 expand

(\frac{x ^{3}}{4} - \frac{1}{x ^{3}})^{2}

expand (2x^{5/3}+3)^2 expand

(2 x^{\frac{5}{3}} + 3)^{2}
