Question 300802
Given: {{{3B^2 - 17B + 22}}}
You still use the unfoil method however you need to include the coefficient.
Find the factors of 22: 1,2,11,22
You need to look at those factors and figure out how to get -17 while using the coefficient with one of the factors.
-17 = -11 - 3*(2)
{{{(3B - 11)*(B - 2) = 3B^2 - 17B + 22}}}
Set that equal to 0 to solve for B
-----------------
{{{3B - 11 = 0}}}
{{{3B = 11}}}
{{{highlight(B = 11/3)}}} or 3.6667
-----------------
{{{B - 2 = 0}}}
{{{highlight_green(B = 2)}}}
