Find all zeros of function and write the polynomial as a product of linear factorsX^3-x^2+9x-9

mart [117]

Answer:

$\large\boxed{x=1\ \vee\ x=-3i\ \vee\ x=3i}$

Step-by-step explanation:

$\text{The zeros:}\\\\x^3-x^2+9x-9=0\\\\x^2(x-1)+9(x-1)=0\\\\(x-1)(x^2+9)=0\iff x-1=0\ \vee\ x^2+9=0\\\\x-1=0\qquad\text{add 1 to both sides}\\x-1+1=0+1\\\boxed{x=1}\\\\x^2+9=0\qquad\text{subtract 9 from both sides}\\x^2=-9$

Round to the near at tenth <br> | 3x + 1 | =22

sdas [7]

Answer:

x =7 x = -7 2/3

Step-by-step explanation:

| 3x + 1 | =22

Absolute value equations have 2 solutions, one positive and one negative

3x+1 = 22 3x+1 = -22

Subtract 1 from each side

3x+1-1 =22-1 3x+1-1 = -22-1

3x= 21 3x = -23

Divide each side by 3

3x/3 = 21/3 3x/3 = -23/3

x =7 x = -7 2/3

C is right. She has partially completed the construction. Her next step is to use the arc markings to determine the radius to construct the circle.
