MAth B Question?? NEED HELp?

Question

1--- 2x/3-4/x=5/3
2--- 1-5/x+6/x2/1-3/x
3----(5x+1)=x+9
4-----2xsquare-x-3 as the product of 2 binomials
5---Factor- 49-xsquare
6----(x/2-1)
OK THANKS Alot people

Answer 1

1--- 2x/3 - 4/x = 5/3
2x^2 - 12 = 5x
2x^2 - 5x - 12 = 0
(2x + 3)(x - 4) = 0
x = - 3/2, 4

2--- 1-5/x+6/x2/1-3/x
undecipherable

3----(5x+1)=x+9
4x = 8
x = 2

4-----2xsquare-x-3 as the product of 2 binomials
(2x + 3)(x - 1)

5---Factor- 49-xsquare
(7 + x)(7 - x)

6----(x/2-1) x/2 ≤ 2
x ≤ 4
