please help me solve 20g^2=16g

Question

anonymous · Answer

Well what do you think you have to do to?

mathstudent55 · Answer

Subtract 16g to the left side and end up with an equation that equals zero. Then factor the left side and set each factor equal to zero. Then solve each equation.

I'm still lost. -____-

mathstudent55 · Answer

20g^2 = 16g
20g^2 - 16g = 0
Now can you factor the left side?

mathstudent55 · Answer

20g^2 - 16g = 0
4g(5g - 4) = 0
4g = 0 or 5g - 4 = 0
g = 0 or 5g = 4
g = 0 or g = 4/5

anonymous · Answer

Ok heres a better way to do it. Since you want to get g by itself you simply divide by 20. Then square both sides and there is your answer.

20g^2/20=16g/20
g^2=4/5
g = rad 4/5or rad 0.80
