Answer:
Imaginary Roots
Step-by-step explanation:
The quadratic equation ax^2 + bx + c = 0 is written in standard form, and the formula is
x = [-b ± √(b^2 - 4ac)]/ 2a
Given:
3x2 - 4x + 5 = 0'
Here a = 3, b = -4 and c = 5
Substituting:
x = [-(-4) ± √((-4)2 - 4 × 3 × 5)]/ (2 × 3)
Further Simplification:
x = [4 ± √(16 - 60)]/6 ----> Discriminant: b^2 - 4ac = -44 < 0.
x = [4 ± √-44]/ 6
Now, we get:
x = [4 ± 2√-11]/ 6
x = [2 ± i √11]/ 3
Therefore, The best description of the roots of the equation 3x2 - 4x + 5 = 0 is imaginary roots.
Answer:
-1/8 is the answer
Step-by-step explanation:
1.) 1st we have to take 1/2x and make the bottom number 4. so we multiply by 2 and you should get 2/4.
2.) so now the equation should be 3/4x + 5 -2/4x = 3. now you take 3/4x and -2/4x and subtract them and you should get 1/4x.
3.) now the equation should look like 1/4x + 5 = 3. now we need to get all whole numbers to one side. so we will subtract 5 from 5 and that will cancel it out and we need to do that to both sides. so we will subtract 5 from 3 and you will get -2.
4.) now the equation should look like 1/4x = -2. now you put a 1 under the 2 to make it a fraction. it should look like 2/1 and then you are going to flip it because that is how you divide fractions. so now your equation should look like 1/4x = 1/2. now you multiply strait across both bottom and top. and you will get x = -1/8 and that is your answer.
hope this helped!
p.s it would be cool if you gave me brainliest.
