Find all real zeros of the polynomials and determine the multiplicity of each. (solve by factoring)

f(x) = x^3 - 6x^2 - 9x + 54

f(x) = x^4 + 5x^3 + 6x^2

1) x= -3, 3, 6

2) x= -3, -2, 0

Step-by-step explanation:

To factor this, we can use grouping

First we can factor the first pair and second pairs of terms

As we have the same factor on each of these, we can combine the like terms to get

This can be factored into

This gives us the zeroes of

x= -3, 3, 6

To factor this one, we first need to factor out a term

This is a quadratic equation that simplifies to

This gives the zeroes of

x= -3, -2, 0

a and c

step-by-step explanation:

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
