Answer: sin(a+b)= sin(a)*cos(b)+sin(b)*cos(a).

Step-by-step explanation: we can write some trigonometric functions in different ways (some more simplified that others), in the case of the given problem, the expanded equivalent of the expression sin(a+b) can be written as follows:

sin(a+b)= sin(a)*cos(b)+sin(b)*cos(a).

Select the two binomials that are factors of this trinomial.

mojhsa [17]

To split this trinomial into two binomials, let's try and find two numbers which add to 6 and multiply to 8. To do this, we can list all the factors of 8 and then choose which factors also add to 6.

Factors of 8: (1, 8), (2, 4)

1 + 8 = 9, meaning that 1 and 8 are not the factors we are looking for. However, 2 and 4 do add to 6. By combining these numbers which an x (so that we can produce the $x^2$ term at the front of the trinomial), we find the binomials:
