Hi there.

4(2 + 3i) - 2(6 - 8i); apply the distributive property.
8 + 12i - 12 - 16i; combine like-terms.
-4 - 4i is your final expression.

I hope this helps!

Factorize (x-3)(x-5)(x-7)(x-9)+15
zhannawk [14.2K]

The expanded form of the equation is x^4-24x^3+222x^2-240+960

<h3>Expansion of expression</h3>

Given the expression below;

(x-3)(x-5)(x-7)(x-9)+15

Expand

(x-3)(x-5)(x-7)(x-9) + 15

(x^2-5x-3x+15)(x^2-9x-7x+63) +15

(x^2-8x+15)(x^2-16x+63) + 15

Expand further to have;

x^4-16x^3+63x^2-8x^3+144x^2-504+15x^2-240x+945+15

x^4-24x^3+222x^2-240+960

Hence the expanded form of the equation is x^4-24x^3+222x^2-240+960
