Write 5x^2 + 30x + 36 in the form 5(x+A)^2+B where A and B are integers to be found.Then write the equation of symmetry for the graph of 5x^2 + 30x + 36

-Take factor of 5 out as seen in question.-Expand the brackets-Then draw a sketch of the graph -Then understand what type of graph it is and what it means about the line of symmetry.
