Use the distributive property to distribute the 5b by the 6b and -10 terms.
Here are two examples of the distributive property:
a(b - c) = ab - ac
6(3b - 8) = 18b - 48

The answer will have only two terms, not three.

anonymous · Answer

11b - 10

mathstudent55 · Answer

5b * 6b = 5 * 6 * b * b = 30b^2
5b * 10 = 5 * 10 * b = 50b
5b(6b - 10) = 5b*6b - 5b*10 = 30b^2 - 50b

mathstudent55 · Answer

11b = 5b + 6b. You added 5b and 6b. You need to multiply them together:
5b * 6b = 30b^2
Also, the -10 inside the parenteses must also be multiplied by 5b, so 5b * 10 = 50b
5b(6b - 10) = 30b^2 - 50b
