Answer 2

Solving the Equation

To solve the given equation, we'll follow the standard order of operations (PEMDAS/BODMAS) to simplify and solve for the variable x.

The given equation is: 0.4x(5+3x) + 0.6 = 0.2x(6x-3)

Step 1: Distribute and Simplify

First, we'll distribute the terms and simplify the equation.

0.4x(5+3x) + 0.6 = 0.2x(6x-3)

0.4x*5 + 0.4x*3x + 0.6 = 0.2x*6x - 0.2x*3

2x + 1.2x^2 + 0.6 = 1.2x^2 - 0.6x

Step 2: Rearrange the Equation

Next, we'll rearrange the equation to set it equal to zero.

1.2x^2 - 0.6x - 2x - 0.6 = 0

1.2x^2 - 2.6x - 0.6 = 0

Step 3: Solve for x

Now, we'll solve the quadratic equation using the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a)

Where a = 1.2, b = -2.6, and c = -0.6

x = (-(-2.6) ± √((-2.6)² - 4*1.2*(-0.6))) / (2*1.2)

x = (2.6 ± √(6.76 + 2.88)) / 2.4

x = (2.6 ± √9.64) / 2.4

x = (2.6 ± 3.1) / 2.4

So, the solutions for x are: x = (2.6 + 3.1) / 2.4 and x = (2.6 - 3.1) / 2.4

By solving these, we'll get the values of x.

This is the detailed solution for the given equation. If you have any further questions or need additional assistance, feel free to ask!
