2 х-5x^2=0

4m^2-3m=0

y^2-2y-8=2y-8

3u^2+7=6u+7

2x - 5x^2 = 0

x (2 - 5x) = 0

x = 0

2 - 5x = 0 = = > 5x = 2 = = > x = 2/5 = 0.4

4m^2 - 3m = 0

m (4m - 3) = 0

m = 0

4m - 3 = 0 = = > 4m = 3 = = > m = 3/4 = 0.75

y^2 - 2y - 8 = 2y - 8

y^2 - 2y - 2y = 0

y^2 - 4y = 0

y (y - 4) = 0

y = 0;

y - 4 = 0 = = > y = 4

3u^2 + 7 = 6u + 7

3u^2 - 6u = 0

u^2 - 2u = 0

u (u - 2) = 0

u = 0

u - 2 = 0 = = > u = 2
