Answer 2

Solving the Equation

To solve the given equation 3x^2 + 4x - 2 / 5 = 3x^2 + 17 / 10, we can follow these steps:

First, let's simplify the equation step by step.

Step 1: Simplify the Equation

The given equation is: 3x^2 + 4x - 2 / 5 = 3x^2 + 17 / 10

Step 2: Isolate the Variable

To isolate the variable, we can start by subtracting 3x^2 from both sides of the equation.

Step 3: Further Simplification

After subtracting 3x^2 from both sides, the equation becomes: 4x - 2 / 5 = 17 / 10

Step 4: Solve for x

To solve for x, we can multiply both sides of the equation by 5 to clear the fraction.

Step 5: Final Calculation

After multiplying both sides by 5, the equation becomes: 20x - 2 = 17

Now, we can solve for x by isolating it on one side of the equation.

Step 6: Isolate x

Adding 2 to both sides of the equation gives us: 20x = 19

Finally, to solve for x, we divide both sides by 20.

Step 7: Final Solution

Dividing both sides by 20 yields: x = 19 / 20

So, the solution to the equation 3x^2 + 4x - 2 / 5 = 3x^2 + 17 / 10 is x = 19 / 20.
