sorry for the kinda slow reply .-.
do you know how to factor?
aka backwards FOILing?

that's good :)
but now we have to do it backwards
x^2 - 8x + 12
= (x)(x) - (6x) - (2x) + (6)(2)
= (x - 6)(x - 2)
can you walk me through it please?
of course :)
first we have to understand that in our equation: \( x^2-6x+8 \)
we have to find two numbers (x + #)(x + #)
that will go here ^ ^
these two numbers should \(multiply~up~to~positive~8\)
so let's first list the pairs of numbers that can multiply up to a positive 8 :)
this would include
\( 1~and~8 \)
can you find a pair that adds up to \(-6\) ?
[adds up like \(-1 + -8 = -9\) ]
ok i see
1 and 8
-1 and -8
2 and 4
-2 and -4
-1 + -8 = -9
-2 + -4 = -6 <-- so the pair of -2 and -4 works
all we have to do now is to plug "-2" and "-4"
into (x + __)(x + __)
to have our factored version of the equation
\(Warning!\) Don't select an answer yet!
(x - 2)(x - 4)
now the "zeros" of this would be when each part is set equal to "zero"
x - 2 = 0 [solve for x]
x - 4 = 0 [solve for x]
noww you will get your answers :)
