You take the coeffeicent of the linear term, half it then square it. giving Now applying the difference of 2 squares and we are finished.
in the part: how do you know where to put the brackets that seperate (+1) and (-7)
In I was looking for a new constant term that would help me make a perfect square. Finidng as this term gave I couldn't just throw away the and to balance the equation I introduced an extra from the found. A perfect square has the from of either or
k one more question. If I were to make this into an equation like this "h=-5(t^2)+10t+35" is it possible to make "h=-5(t^2)+10t+35" into a(x-s)(x-t)? Without graphing it?
