Factor the expression below by using the distributive property and grouping the first two terms together AND use the distributive property and group the last two terms together. x^3 + 7x^2 - 6x - 42. Show your work, please.
The hint given is wrong. You need to group the terms as follows.
\(x^3 + 7x^2 -6x-42 = \\ (x^3 -6x) + (7x^2 - 42) = \\ x(x^2 - 6) + 7(x^2 - 6) = \\ (x+7)(x^2-6)\)
