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.

Converting a fraction into a decimal is dividing the fraction's numerator (the top number) by its denominator (the bottom number).
If you want to convert 3/8 into a decimal, divide 3 by 8. Because 8 can't go into 3, you have to add a zero to 3, making it 30. That's how you convert fraction to decimal.

To convert fraction to percent Divide the top of the fraction by the bottom,
Then multiply the result by 100.
