Which of the following is a polynomial with roots 4, 6, and −7

Answer 1

y=x^3-3x^2-24x+42
y=x^3-3x^2-46x+168
y=x^3-24x^2-42x+46
y=x^3-24^2-46x+168

Answer 2

A polynomial with roots \(\large\color{blue}{ \displaystyle \rm a }\), \(\large\color{green}{ \displaystyle \rm b }\), and \(\large\color{red}{ \displaystyle \rm c }\)

Can be written out as: \(\large\color{black}{ \displaystyle y=(x-\color{blue}{\rm a})(x-\color{green}{\rm b})(x-\color{red}{\rm c}) }\)

(then you will expapnd \(\rm \small YOUR \) expression that you get after using this rule.

Answer 3

take it as:

1) your \(\large\color{black}{ \displaystyle \color{blue}{\rm a} }\) is 4
2) your \(\large\color{black}{ \displaystyle \color{green}{\rm b} }\) is 6
3) your \(\large\color{black}{ \displaystyle \color{red}{\rm c} }\) is -7

Answer 4

the answer is the third one

Answer 5

I doubt that....

Answer 6

last one

Answer 7

please show your work so that I can tell where the mistake in your expansion is...

Answer 8

the first one

Answer 9

(x-4)(x-6)(x+7)
(x^2-6x-4x+24)(x+7)
(x^2-10x+24)(x+7)
x^3+7x^2-10x^2-70x+24x+168...can you simplify it...

Answer 10

so which one is it?
