Answer this in pictures and number of words

Tom's solution is incorrect.

Step-by-step explanation:

When you add 3/6 + 1/2 it equals ?.

3 + 1  = ?

6 + 2 = ?

We must have common denominators to do this problem.

So we must have 6 as our common denominator.

So 2 x 3 = 6. But we have to do the same to the Numerator.

So 1 x 3 = 3.

Now our problem is 3/6 + 3/6 = ?

3 + 3 = 6/6. Or 1

1 does not equal 4/12 or 1/3. So it makes it Incorrect.

What you should say:

Tom is incorrect, it is because 3/6 + 1/2 = 1, 1 does not equal 4/12 or 1/3. So, it makes it reasonable for the correct answer to be Incorrect

Step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
