Question 1925: z(5z-1)=3z(z+3) solve by suitable methods without decimals
Answer by longjonsilver(2297)   (Show Source):
You can put this solution on YOUR website! multiply out the brackets, collect like terms together and bring them all onto the same side of the "=", so that it all equals zero, then factorise...see solution 1926.
If you cannot factorise...use the quadratic formula. Again look at my recent answers for this.
