Question

multiplying polynomials

(5a+6)(a-1)

Answer 1

5a^2-5a+6a-6=5a^2+a-6

Answer 2

5a^2-5a +6a-6
5a^2+a-6

Answer 3

FOIL... (first outter inner last) multiply the terms in that order

Answer 4

5a^2-5a+6a-6
=5a^2+a-6

Answer 5

\[5a^2 - 5a + 6a - 6 = 5a^2 + a - 6\]

Answer 6

Use the foil method as mentioned by SJSharks003. FOIL stand for (First-outer-inner-last)

(First) Multiply 5a by a to get \[5a^2\]. (Outer) Then multiply 5a by -1 to get -5a. (Inner) Then multiply 6 by a to get 6a. (Last) Then multiply 6 by -1 to get -6.

Hope this helps :D
