What is cross multiplication?

In mathematics, cross multiplication is a technique that is mostly used to find an unknown number. By doing this technique, you make that unknown number the subject of the formula of the equation we are looking for.

From the given information; we have:

[tex]\mathbf{\dfrac{15}{(a^2 -1)} = \dfrac{5}{(2a -2)}}[/tex]

By cross multiplying, we multiply the numerator of each fraction with their adjacent denominators,

i.e.

15(2a - 2) = 5(a² - 1)
