n3 + 3n2 + 4n + 12 = (n3 + 3n2) + (4n + 12) = n2(n + 3) + 4(n + 3) = (n2 + 4)(n + 3).
a2 - 4a + 4
(2x+4)(x+1)
(3x + 4)(3x + 4)
That's 44v + 4 which factors to 4(11v + 1)
n3 + 3n2 + 4n + 12 = (n3 + 3n2) + (4n + 12) = n2(n + 3) + 4(n + 3) = (n2 + 4)(n + 3).
15x - 3xy = 3x(5 - y) 20 - 4y = 4(5 - y) 15x - 3xy + 20 - 4y = (3x + 4)(5 - y)
Not factorable
Do in this order. 1. All, find the gfc 2. Binomial, factor as difference of squares, sum of cubes, difference of cubes. 3. Trinomial, factor as a quadratic. 4. 4 or more terms, factor by grouping.
(2x + 1)(x + 4)
a2 - 4a + 4
(2x+4)(x+1)
If there are 4 or more terms in a problem, and none are like terms.
(3x + 4)(3x + 4)
4(x + 1)(x + 1)
(x-1)(x+4)
That's 44v + 4 which factors to 4(11v + 1)
