You can't solve for the zeros by factoring because the function is not factorable.

I'll show you what happens:
f(x) = 6x^2 + 6x + 12

To solve for the zeros (when f(x)=0), set f(x) equal to 0.
0 = 6x^2 + 6x + 12

First you can factor out a 6.
0 = 6(x^2 + x + 2)

Divide by 6.
0 = x^2 + x + 2

Now you need two integers that add up to the coefficient of x (1) and multiply to the product of the last term and the coefficient of x^2. This number is 2.
No two integers add up to 1 and multiply to 2.

Tony's cat weighs c pounds. Three months from know, the cat's weight is expected to increase by 12.5% Write two expressions to r
horrorfan [7]

Answer:

Step-by-step explanation:

Tony's cat weighs c pounds. This means that the cat currently weighs c pounds.

Three months from know, the cat's weight is expected to increase by 12.5%. This means that in three months time, the weight of the cat is expected to be the sum of its current rate × 12.5 % of its current rate. It becomes

c + 12.5/100 × c = c + 0.125c

= 1.125c

So the two expressions that represent the cat's weight in three months would be

1) three months from now, the cat's weight will increase by 0.125c

2) three months from now, the new weight of the cat will be 1.125c
