Factore each of the following: (I DONT UNDERSTAND HOW TO DO THIS?)

1) (2/3)x^(5/2) + 2x^(3/2) + 14x^(1/2)

2) (2/3)x^(3/2) + (4/5)x^(5/2)

4) 4y^2 -(2/7)y^(7/2)

factor out $\textcolor{red}{2x^{\frac{1}{2}}}$ from each term

2) (2/3)x^(3/2) + (4/5)x^(5/2)

factor out $\textcolor{red}{2x^{\frac{3}{2}}}$ from each term

4) 4y^2 -(2/7)y^(7/2)

you figure out the last one ... what factors do the two terms have in common?
