The first term = \frac{y^2}{y-3}
The second term = \frac{y^2-y-6}{y^2+y} =  \frac{(y-3)(y+2)}{y(y+1)} ⇒ factoring the numerator and denominator

multiplying the both terms:
\frac{y^2}{y-3} * \frac{y^2-y-6}{y^2+y} = \frac{y^2}{y-3} * \frac{(y-3)(y+2)}{y(y+1)} 

= \frac{y^2}{y} * \frac{(y-3)(y+2)}{(y-3)(y+1)} =  \frac{y(y+2)}{y+1}

You have the following expressions given in the problem above:

 (y^2/y-3)(y^2-y-6/y^2+y)
 
 By applying the exponents properties, you can simplify it, as it shown below:

 (y^2/y-3)(y^2-y-6/y^2+y)
 (y^4-y^3-6y^2)/(y^3+y^2-3y2-3y)
 (y^4-y^3-6y^2)/(y^3-2y2-3y)

 Then, you have:
 y^2(y^2-y-6)/y(y^2-2y-3)
 (y^2-y-6)/(y^2-2y-3)

 The answer is: (y^2-y-6)/(y^2-2y-3)

Aleks04 [339]
MCE = 360 - (150 + 70 + 50)
mCE = 360 - 270
mCE = 90

<CDE = 1/2(mBE + mCE)
<CDE = 1/2(150 + 90)
<CDE = 1/2(240)
<CDE = 120

answer
<CDE = 120°
