уравнения
5х²-3х=0
х²-25=0
х²-9=0
х²-1=0
64-х²=0
25-х²=0

Answer 1

1. 5x^2-3x=0     2. x^2-25=0            3. x^2-9=0             4. x^2-1=0
    x(5x-3)=0           (x-5)(x+5)=0           (x-3)(x+3)=0         (x-1)(x+1)=0
    x=0  5x=3            x=5    x=-5              x=3     x=-3          x=1  x=-1
          x=3/5

5. 64-x^2=0               6. 25-x^2=0
   (8-x)(8+x)=0                (5-x)(5+x)=0
    x=8   x=-8                    x=5   x=-5
