To determine which one is correct, we notice that the middle term in the trinomial 
is negative, hence when we multiply the inner terms and then the outer terms, the negative term should have the larger coefficient. Looking at the possibilities we see that the correct factorization is 
since multiplying the outer terms give us 
and multiplying the inner terms gives us 
, which add up to the 
as desired. Thus (b) is the correct answer.
making (b) the correct answer.
and add 12 to both sides to get b = 28 which is answer (a).
Thus, (a) is the correct answer.
To move the decimal point in both the numerator and the denominator one spotto the right, multiply the top and the bottom by 10 to get
to the denominator and the 
to the numerator and make the exponents positive. Thus

factors, we look at the factorizations of

, and 
and 
respectively. (Notice that the 1 and the 3 will have opposite signs since theconstant term is -3.) Thus we get

where

-intercept. Since we are told that 
, all we need to do is find the value of 
. Since the line passes through the point (-1,5), we know that when 
. Substituting we get:
. Which is answer (c).
. Since the constant term (9) is positive, it means that both factors of 9 have the same sign and since the middle term 
is negative they both must be negative. Thus the factors of 9 are -1 and -9 or -3 and -3. Hence
. However, the only way a product of two numbers can be 0 is if one of the numbers is 0. Thus,
