the square of a binomial will always result in the trinomial a2 + 2ab + b2 if the binomial consisted of the square of the sum of two variables (a + b)2 ; or it will result in the trinomial a2 - 2ab + b2 if the binomial consisted of the square of the difference between two variables (a - b)2
points that lie on the same line (so that the gradient is the same at each point).
the limit of the average gradient as the change in x tends towards zero.
in set theory, a union between two or more data sets refers to all the elements in the data sets...
the axis of symmetry; or the line about which a figure is reflected.
