-3 (2x+5) (x^2-3x+2)

For first bracket
-3 x 2x = -6x
-3 x 5 = -15

Therefore simplified:

-6x - 15 (x^2 - 3x + 2)

Simplify second bracket

-15 * x^2 = -15x^2
-15 x - 3x = 45x
-15 x 2 = -30

Therefore

-6x - 15 - 15x^2 + 45x -30

Now bring all like times together

-6x + 45x - 15 - 30 - 15x^2

Then simplify for answer

-39x - 45 - 15x^2
