Zeros :-1,1,3;degree:3
forsale [732]

Answer:

y = x³ - 3x² - x + 3

Step-by-step explanation:

Given the zeros x = - 1, x = 1 and x = 3 then

(x + 1), (x - 1) and (x - 3) are the factors and the polynomial is the product of the factors, hence

y = a(x - 1)(x + 1)(x - 3) ← a is a multiplier

let a = 1 and expand the factors

y = (x² - 1)(x - 3)

  = x³ - x - 3x² + 3

  = x³ - 3x² - x + 3 ← in standard form

3. Factor.
sleet_krkn [62]
It seems that some the work is already here, but I'd be glad to!! So for #3 which is 9x^2+15x, we can factor out both a 3 and an x (3x) so we know that 3x * 3x =9x^2 and 3x * 5 = 15x so once we take the 3x out of the equation, we are left with 3x(3x+5) and that's as far as you can factor.
For #4, we see that the common factor is 10m because 10m * 2n = 20mn and 10m * 3 = 30m so once we take 10m out of the original, it becomes 10m(2n-3)
For #5, this one the common factor is 4xy because 4xy * 2xy=8x^2y^2 and 4xy*x= 4x^2y and 4xy*3=12xy so once we take the 4xy out of the equation, it becomes 4xy(2xy-x-3)
Hope this helps!
