a. f(x) = x2-5x-14 b. f(x) = 9x2 -4
c. f(x) = 6x2 -x -12
factor the following
c.
Again, simply find the numbers that multiply to -12 and add to -x. Always remember the last sign in the equation, it is very important. If it is negative, the signs will be difference in the set of brackets. If it is positive the signs will be the same, they will both be what the first sign is.
