Question

(12a + 4)(3a - 1) = 0

Answer 1

FOIL
throw the aluminum foil onto it
that's how

Answer 2

i don't even know what foil means
let me look it up

Answer 3

FOIL
first, outside, inside, last
FOIL

Answer 4

maybe we don't even need to FOIL. really what do you want? what are you looking for? what is this i don't even know? solve for 'a' or what? aluminum foil on baked potato?

Answer 5

distribute it out
36a^2--4
(6a-2)(6A+2)=0
a=1/3,a=-1/3

Answer 6

You have the product of two binomials, which equals zero:
\[(12a + 4)(3a - 1) = 0\]

Now for the sake of simplicity in explanation, lets call \((12a + 4) = A\), and \((3a - 1) = B\), so we have \(A * B = 0\)
The product of two things is zero only if one or both of the thing are zero, so
\(A = 0\) is a solution, and \(B = 0\)

which gives
\(12a + 4 = 0\), \(a = -{1 \over 3}\) or
\(3a - 1= 0\), \(a = {1 \over 3}\)
