what are the zeros of the polynomial function f(x)=x(x-4)(x+9)

a. 0,4,-9
b. 1,-4,9
c. 0-4,9
d. 1,4, -9

1. x = 0, 4, -9

2. x = 3, 3, -5

3. 2x^3 - 9x^2 + 7x + 6

4. x = -6, -8, -15

5. 2x^3+10x^2+12x

Factor out the common factor:

2x (x^2+5x+6 )

Factor what's left in parentheses:

2x (x + 2) (x + 3)

6. x = 0, 4, -9

Step-by-step explanation:

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
