Which question are you talking about 1 or 2?
Solution:
iv) Given equation: 
Since we are given two variables, we need to split the original expression into two quadratic expressions as
Factoring x first:
= 
= 
Factoring y now:
= 
= ![-1[ y(y+1) + 1(y+1)]](https://tex.z-dn.net/?f=-1%5B%20y%28y%2B1%29%20%2B%201%28y%2B1%29%5D)
= ![-1 [(y+1)(y+1)]](https://tex.z-dn.net/?f=-1%20%5B%28y%2B1%29%28y%2B1%29%5D)
= 
Therefore, the original expression becomes
Not all triangles have right angles. A triangle is simply a closed figure with three sides and three angles, the sum of the degrees of which add up to 180°.
For instance, an equilateral triangle will will have all three angles equal to each other (60°, 60°, 60<span>°).
Some triangles may have right angles (90</span><span>°), but not all do.
