Both have magnitudes of A, so they are equal distances and, by the definition of additive inverses, A + (-A) = 0 and that means that they are opposite. Of course, they need not be opposite distances: they could be opposite times, or opposite amounts of money.

It means you are required to "solve" a quadratic equation by factorising the quadratic equation into two binomial expressions. Solving means to find the value(s) of the variable for which the expression equals zero.

Factorising 15x-27xy gives 3x (5 - 9y).Factorising is to express a number or expression as a product of factors.When factorising always look for common factors. To factorise (15x-27xy) look for the highest factor between the two terms (3x). 15x - 27y = 3x (5 - 9y)
