Find all zeros and write in factored form<br> (x-5)(3x^2-8x+6) =0

Snezhnost [94]

Answer:

x = 5, 4/3+i√2/3, 4/3-i√2/3.

Step-by-step explanation:

(x-5)(3x^2-8x+6) =0

This is in factored form already. 3x^2 - 8x + 6 cannot be factored, it is prime.

One zero is x = 5.

3x^2-8x+6 = 0 Using the quadratic formula:

x = [8 +/- sqrt (64 - 4*3*6]) / 6

x = 4/3 +/- sqrt (-8) / 6

x = 4/3 +/- 2sqrt2 i / 6

x = 4/3 +/- i√2 / 3.

The point A(-2, 3) is translated using T: (x,y) → (x + 4, y + 2). What is the distance from A to A'? 2 5 2

stepan [7]

For this case, we have that by definition, the distance between two points is given by:

$d = \sqrt {(x_ {2} -x_ {1}) ^ 2+ (y_ {2} -y_ {1}) ^ 2}$

We have to:

$A: (x_ {1}, y_ {1}) = (- 2,3)\\A ':( x_ {2}, y_ {2}) = (x + 4, y + 2) = (- 2 + 4, 3 + 2) = (2,5)$

Substituting:

$d = \sqrt {(2 - (- 2)) ^ 2+ (5-3) ^ 2}\\d = \sqrt {(4) ^ 2 + (2) ^ 2}\\d = \sqrt {16 + 4}\\d = \sqrt {20}$

Answer:

$d = \sqrt {20}$
