Question

How do you factor `96xy + 112x + 84y + 98` by grouping?

Answer 1

`96xy+112x+84y+98 = 2(8x+7)(6y+7)`

Explanation:

Separate out the common scalar factor `2` and factor by grouping:

`96xy+112x+84y+98 = 2((48xy+56x)+(42y+49))`

`color(white)(96xy+112x+84y+98) = 2(8x(6y+7)+7(6y+7))`

`color(white)(96xy+112x+84y+98) = 2(8x+7)(6y+7)`
