Solving the Equation: (2x-3)(2x+3)-(x-1)^2-3x(x-5)=-44

This article will guide you through the steps to solve the equation (2x-3)(2x+3)-(x-1)^2-3x(x-5)=-44.

Step 1: Expand the expressions.

We begin by expanding the expressions on the left-hand side of the equation:

  • (2x-3)(2x+3) is a difference of squares pattern, which expands to 4x² - 9
  • (x-1)² expands to x² - 2x + 1
  • 3x(x-5) expands to 3x² - 15x

Now our equation looks like this:

4x² - 9 - (x² - 2x + 1) - (3x² - 15x) = -44

Step 2: Simplify the equation.

Next, we simplify the equation by removing the parentheses and combining like terms:

4x² - 9 - x² + 2x - 1 - 3x² + 15x = -44

Combining terms: 0x² + 17x - 10 = -44

Step 3: Isolate the x term.

Now, we want to isolate the x term. Add 10 to both sides of the equation:

17x = -34

Step 4: Solve for x.

Finally, divide both sides by 17 to solve for x:

x = -2

Conclusion

Therefore, the solution to the equation (2x-3)(2x+3)-(x-1)²-3x(x-5)=-44 is x = -2.
