Answer:
Explanation:
X^2 +23x+132=0 you find two numbers that will multiply to give 132 and add to give 23
In this case the two numbers will be +12 and also +11
12*11=132 and +12+11 =23
X^2 + 12x +11x +132=0
Factor by grouping
X(x+12)+11(x+12) =0
(X+11) (x+12)=0
X +11=0
So x=-11
X+12=0
So x-12
There your solution will be
X=-11 or -12
