Question

8х²-3/5-5-9х²/4=2 решите пж уравнение

Answer 1

64-3/5-5-9x^2/4=2
59-3/5-9x^2/4=2
59-3/2-9x^2/4=2
5*59-3/5-9x^2/4=2
295-3/5-9x^2/4=2
292/5-9x^2/4=2
292-9/4x^2=2
-9/4x2=2-292/5
-9/4x^2=5*2-292/5
-9/4x^2=10-292/5
-9/4x^2=-282/5
x^2=-282/5/(-9/4)
x^2=-282/5*(-4/9)
x^2=-94/5*(-4/3)
x^2=94/5*4/3
x^2=944/5*3
x^2=376/15
