For binomials of the form (x - y) ^ n explain how to determine the sign of a term without writing out the entire expansion
Mnenie [13.5K]

Answer:

When raising an expression of that format to any power, after grouping like terms, you'll always find that the odd numbered terms are positive, and the even numbered terms are negative.

For example:

(x - y)² = x² − 2xy + y²

(x - y)³ = x³ − 3x²y + 3xy² − y³

(x - y)⁴ =x⁴ − 4x³y + 6x²y² − 4xy³ + y⁴

etc.

igor_vitrenko [27]
Based off of  what I can see in the  photo (its too blurry to know for sure) and what I think you're asking:

The angle of a triangle always adds up to 360degrees, so base it on that and the acute and obtuse  angles  and get the degrees from there, the angle would be those degrees you find or <10, 5, 4 (what I assume  is a 5)
