P(x) = x^4 - 9x^2 - 4x + 12
P(1) = 1^4 - 9(1)^2 - 4(1) + 12 = 1 - 9 - 4 + 12 = 0
x = 1 is a root.
By dividing the polynomial by x - 1, gives other roots as 3 and -2
Answer:
It's B
Step-by-step explanation:
Just divide y by x. For example: 6.6 / 6 = 1.1. This would be B! Hope this helps!

Answer:
<h2><u>7</u>x - <u>7</u>y + <u>21</u> </h2>
Step-by-step explanation:
7(x - y + 3)
=> 7 × x - 7 × y + 7 × 3
=> <u>7</u>x - <u>7</u>y + <u>21</u>
