HELP!!!!!! Choose the correct simplification of the expression (3x − 6)(2x2 − 4x − 5)

OpenStudy (anonymous):

a. 6x3 − 24x2 + 9x − 30 b. 6x3 + 9x + 30 c. 6x3 − 24x2 + 9x + 30 d. 6x3 − 24x2 + 39x + 30

Hint: (a+b)(c+d+e) = a(c+d+e) + b(c+d+e)

jimthompson5910 (jim_thompson5910):

this is using the distributive property

jimthompson5910 (jim_thompson5910):

so if we use this hint, we would go from (3x-6)(2x^2 - 4x - 5) to 3x(2x^2 - 4x - 5) - 6(2x^2 - 4x - 5) I'll let you finish
