4y^2-10y=0

To solve the equation 4y^2 - 10y = 0, you can factor out the common factor of y:

y(4y - 10) = 0

Now set each factor equal to zero:

y = 0

4y - 10 = 0

To solve the second equation, add 10 to both sides:

4y = 10

Divide both sides by 4:

y = 2.5

So the solutions to the equation 4y^2 - 10y = 0 are y = 0 and y = 2.5.
