Answer:
Step-by-step explanation:
50x^2 - 72 = 0
2(25x^2 - 36) = 0
2(5x + 6)(5x - 6) = 0
5x + 6 =0; x = -6/5
5x - 6 = 0; x = 6/5
Answer
x = ± 6/5
----------------------
9x^2 + 6x = 10
Divide both sides by 9
x^2 + 2/3 x = 10/9 
b/2 = 2/3 * 1/2 = 2/6 = 1/3
As you know (1/3)^2 = 1/9
so add both sides by 1/9
x^2 + 2/3 x + 1/9 = 10/9 + 1/9
(x + 1/3)^2 = 11/9
x + 1/3 = ±√11/9
x = ± √11 / 3  - 1/3
Answer:
x = ± √11 / 3  - 1/3

Take out a 2 to begin with.
2(25x^2 - 36)    This is the difference of squares (inside the brackets). Factor.
2*(5x - 6)(5x + 6)
