Re: Solve the following equations for X...

hi ConfusedDue2SchoolSucks

Welcome to the forum.

What is the complete question for Q1 and Q2 ?

The third factorises like this

3x^2+29x+18=0 = (3x + ?) (x +  # )

The numbers to put in place of the ? and # are such that ? times # = 18     and 3# + ? = 29.  It shouldn't be hard to find them.
