Factor x2-12x-13 using the AC method.
Tap for more steps…
Consider the form x2+bx+c. Find a pair of integers whose product is c and whose sum is b. In this case, whose product is -13 and whose sum is -12.
-13,1
Write the factored form using these integers.
(x-13)(x+1)=0
(x-13)(x+1)=0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x-13=0
x+1=0
Set the first factor equal to 0 and solve.
Tap for more steps…
Set the first factor equal to 0.
x-13=0
Add 13 to both sides of the equation.
x=13
x=13
Set the next factor equal to 0 and solve.
Tap for more steps…
Set the next factor equal to 0.
x+1=0
Subtract 1 from both sides of the equation.
x=-1
x=-1
The final solution is all the values that make (x-13)(x+1)=0 true.
x=13,-1
