Answer:
The solution of given equation is ( - 1 + 2 i ) , ( - 1 - 2 i )
Step-by-step explanation:
Given equation as :
3 x² + 6 x +15 = 0
The value of x fro the quadratic equation a x² + b x + c = 0 is obtained as
x =
So , from given eq , the value of x is now obtain as
x =
Or, x =
Or, x =
∴ x = ( - 1 + 2 i ) , ( - 1 - 2 i )
Hence The solution of given equation is ( - 1 + 2 i ) , ( - 1 - 2 i ) Answer
Answer:
A rational number is a number that can be expressed as a fraction (ratio). This includes whole numbers, square roots that can be solved evenly, negatives, decimals, and repeating decimals that can be solved with a fraction.
- ↔ .5
- 5 ↔ 5.0
- ↔ 2.0
- -13 ↔ -13.0
- 0.38462... ()
An irrational number is a number that is NOT rational. It's the complete opposite!
- π ↔ 3.14159
- .13133133...
- ↔ 0.86603...
- - ↔ -2.23607...
- ↔ 2.23607...
Hope this helps!!!
