Answer 2

It seems like you have an equation that you'd like to solve. Let's simplify and solve it step by step:

2x² + x - 28 = 3x - 2x + 4

First, let's combine like terms on both sides of the equation:

2x² + x - 28 = x + 4

Next, let's move all the terms to one side of the equation to set it equal to zero:

2x² + x - x - 28 - 4 = 0

Now, simplify further:

2x² - 28 - 4 = 0

Combine the constants:

2x² - 32 = 0

Now, we have a quadratic equation in the form of ax² + bx + c = 0, where a = 2, b = 0, and c = -32.

To solve for x, you can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

In this case:

x = (0 ± √(0² - 4 * 2 * (-32))) / (2 * 2)

x = (0 ± √(0 + 256)) / 4

x = (0 ± √256) / 4

x = (0 ± 16) / 4

Now, calculate the two possible solutions:

1. x = (0 + 16) / 4 = 16 / 4 = 4
2. x = (0 - 16) / 4 = -16 / 4 = -4

So, the solutions to the equation 2x² + x - 28 = 3x - 2x + 4 are x = 4 and x = -4.
