Answer 2

The answer is 84$x^{5}$ + 774$x^{4}$ + 2694x³ + 4374 x² + 3270x + 900.

Given: 1) x + 5x + 5

           2) x + 5x +6

           3) x + 6x + 5

           4) x² + 5x + 6

To Find: the expansion of the given expression

Solution

The given expression is

(x + 5x + 5) (x + 5x +6) (x + 6x + 5) (x² + 5x + 6)

= (6x + 5) (6x + 6) (7x + 5) (x² + 5x + 6)

Multiplying the 1st two expressions,

= (12x² + 12x + 30x + 30) (7x + 5) (x² + 5x + 6)

= (12x² + 42x + 30) (7x + 5) (x² + 5x + 6)

Multiplying the next two expressions,

= (84x³ + 294x² + 210x + 60x² + 210x + 150) (x² + 5x + 6)

= (84x³ + 354x² + 420x + 150) (x² + 5x + 6)

= 84$x^{5}$ + 354$x^{4}$ + 420x³ + 150x² + 420$x^{4}$ + 1770x³ + 2100x² + 750x + 504x³ + 2124x² + 2520x + 900

=  84$x^{5}$ + 354$x^{4}$ +  420$x^{4}$ + 420x³ + 1770x³ + 504x³ + 150x² + 2100x² + 2124x² + 750x +  2520x + 900

= 84$x^{5}$ + 774$x^{4}$ + 2694x³ + 4374 x² + 3270x + 900

Answer) The expanded value is 84$x^{5}$ + 774$x^{4}$ + 2694x³ + 4374 x² + 3270x + 900.
