Hello :
x²+x - 2 =0
a=1 b=1 c = -2
<span>The sum of the roots is : S = -b/a
</span>S = - 1/1 = -1
Ok, for multiplication of fractions you do not need a common denominator so multiply top by top and bottom by bottom... let me know what you get
565.487 units cubed
hope this helps:)
Triangle? because when you rotate it each part will be a bit different
