Question

3. What is a polynomial function in standard form with zeroes 1, 2, –3, and –3? (1 point)g(x) = x4 + 3x3 –7x2 – 15x + 18
g(x) = x4 + 3x3 –7x2 + 2x + 18
g(x) = x4 – 3x3 + 7x2 + 15x + 18
g(x) = x4 – 3x3 –7x2 + 15x + 18
could you show me step by step please

Answer 1

g(x) = (x - 1)(x - 2)(x + 3)(x + 3)

That accounts for all of your zeros as you will see that this function is zero for all of the above zeros. Now, just multiply out.

Answer 2

This fits the form of g(x) = (x - x1)(x - x2)(x - x3)(x - x4)
where x1 = 1, x2 = 2, x3 = -3 = x4

Answer 3

How are you doing with this?

Answer 4

bad i have more like this can u show me each step then tht anser

Answer 5

(x - x1)(x - x2) = x(x - x2) - x1(x - x2) = x^2 - (x)(x2) - (x)(x1) + (x1)(x2)

And just keep using the distributive law of multiplication.

Answer 6

i dont no that law that why i wahnt u to show each step then the ansers

Answer 7

I just showed you the steps in my last post. That is the distributive law in action. Now it is up to you to try to work out the answer.
