Pulling out like terms
4.1 Pull out like factors :
64m4 - 32m2 - 12 = 4 • (16m4 - 8m2 - 3)
Trying to factor by splitting the middle term
4.2 Factoring 16m4 - 8m2 - 3
The first term is, 16m4 its coefficient is 16 .
The middle term is, -8m2 its coefficient is -8 .
The last term, "the constant", is -3
Step-1 : Multiply the coefficient of the first term by the constant 16 • -3 = -48
Step-2 : Find two factors of -48 whose sum equals the coefficient of the middle term, which is -8 .
-48 + 1 = -47
-24 + 2 = -22
-16 + 3 = -13
-12 + 4 = -8 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -12 and 4
16m4 - 12m2 + 4m2 - 3
Step-4 : Add up the first 2 terms, pulling out like factors :
4m2 • (4m2-3)
Add up the last 2 terms, pulling out common factors :
1 • (4m2-3)
Step-5 : Add up the four terms of step 4 :
(4m2+1) • (4m2-3)
Which is the desired factorization
