x^2+bx+c
Steps to factor trinomials
Use example below:
X^2+11x+18
 1. T chart
 2. Factor "c" c goes under products
 Find all factors of "c" or in this case, 18(1,18,2,9,3,6)
 3. Add factor pairs together in chart, (1+18,2+9,3+6)when they add up to "b"(in this case, 11), you have your two numbers, end up with (x+2)(x+9) can be reversed due to communitive property of multiplication

N^26n+8
 8"c":(1)(8) added together is 9
 (2)(4) added together is 6 (hint: this is right)
 These are the only combinations. Note that 2 added to 4 is equal to 6, which is the "b."
 So, your answer will look like:
 (x+(2))(x+(4)) Or, when simplified, (x2)(x4)

X^2+3x=18
Solve for x
 X^2+3x18=0
 Factor into (x3)(x+6)=0
 So x is equal to 3 or 6
