15 a2 − 1 = 5 2a − 2 which equation results from cross-multiplying? a.) 15(a2  – 1) = 5(2a  – 2)b.) 15(2a  – 2) = 5(a2  – 1)c.) 15(a2  – 1)(2a  – 2) = 5(2a  – 2)(a2  – 1)

Option (b) is correct.

equation results from cross-multiplying.

Step-by-step explanation:

 Given : expression

We have to find the results obtained from cross-multiplying the given expression and choose the correct option from given options.

Consider the given expression

Cross multiply  is done by Multiplying the top and bottom of the first fraction by the bottom number of the second fraction.

Thus, for the given expression

We have,

Thus, option (b) is correct.
