Find the solutions to the equation below 30x^2-28x+6 =0
Naddik [55]

For this case, we have the following equation of the second degree:

30x ^ 2-28x + 6 = 0

If we divide between 2 on both sides of the equation, we will have:

15x ^ 2-14x + 3 = 0

Where:

a = 15\\b = -14\\c = 3

The solutions will come from:

x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2 (a)}

Substituting:

x = \frac {- (- 14) \pm \sqrt {(- 14) ^ 2-4 (15) (3)}} {2 (15)}\\x = \frac {14 \pm \sqrt {196-180}} {30}\\x = \frac {14 \pm \sqrt {16}} {30}\\x = \frac {14 \pm4} {30}

So, we have:

x_ {1} = \frac{14 + 4} {30} = \frac {18} {30} = \frac {18} {30} = \frac {3} {5}\\x_ {2} = \frac {14-4} {30} = \frac {10} {30} = \frac {1} {3}\\

Answer:

x_ {1} = \frac {3} {5}\\x_ {2} = \frac {1} {3}

Option A

Option E
