Choose the appropriate simplified expression.
1. 8x^210x+3/6x^2+3x3
2. (x^24/x^21)*(x+1/x^2+2x)
3. (7/5y+25)(4/3y+15)
4. (x^2/x^2+2x+1)/(3x/x^21)
5. (2x+4/3x3)*(12x12/x+5)
6. (7/2xy^2)+(3/8x^2y)
7. (x^216/2x+8)/((x4)^2/8x32)
8. 5(4x^25x+1/x^2x)
9. 1/3x/5/6y

Use Quadratic Formula.
1. (x3/4)(x1/2) / (x1/2)(x+1) =
(x3/4) / (x+1).
2. (x+2)(x2)/(x+1)(x1) * (x+1)/x(x+2)= (x2)/x(x+1).
3. (7y/5+25)  (4y/3+15) =
7y/5 + 25  4y/3  15 =
Common denominator = 15.
21y/15 + 25  20y/15  15 =
y/15 + 10.
