When is factoring by grouping easier to use. How many terms must you have to have ?
Karo-lina-s [1.5K]
You must have 4 terms for factoring by grouping to be easier to use.

For example...
x^2 + 10x + 2x + 20
(x^2 + 10x) + (2x + 20)
x(x+10) + 2(x+10)
(x+2)(x+10)

The first line, the expression x^2+10x+2x+20, has four terms.

Note: Just because you have four terms doesn't automatically guarantee you can factor

You're solving an equation approximating the number of farm.incidents in Wales and England between 1980-88.

F = 3500
3500 = 250x - 493000
3500 + 493000 = 250x
496500 = 250x
496500/250 = x
1986 = x
