Find the solutions to the equation below 30x^2-28x+6 =0
2 answers:
Answer:
Option A and E are the correct options.
Step-by-step explanation:
30x²-28x+6=0
2(15x²-14x+3) = 0
Or 15x²-14x+3 = 0
15x²-9x-5x+3 = 0
3x(x-3) - 1(5x-3) = 0
(3x-1)(5x-3) = 0
Now by the zero product rule
3x-1 = 0
3x = 1
x = 1/3
And (5x-3) = 0
5x = 3
x = 3/5
So two solutions are (1/3, 3/5).
Therefore options A and E are the correct options.
For this case, we have the following equation of the second degree:
If we divide between 2 on both sides of the equation, we will have:
Where:
The solutions will come from:
Substituting:
So, we have:
Answer:
Option A
Option E
