The area of a rectangular garden is given by the trinomial #x^2+6x-27#. What are the possible dimensions of the rectangle?

Explanation:
This needs to be double checked but I'm guessing you just solve the quadratic formula to find values for
If so, then all you do is factorise and solve, factorising a quadratic involves two rules the numbers in the brackets have to sum to make
9 and -3 multiply to make -27 and add to make 6 therefore
since this is a quadratic and equals zero that tells you that either one of the brackets are equal to zero (as anything multiplied by zero is zero)
Explanation:
This is probably just supposed to be a question about factoring:
But the factors don't really constrain the rectangle so this isn't a very good question.
