Part 1

Solve the equation.

StartRoot 5 x plus 44 EndRoot5x+44minus−99equals=33xminus−55

Solution

The given equation is:

5x+4499=33x55\sqrt{5x + 44} - 99 = 33x - 55

Step 1: Simplify both sides of the equation.

Start by isolating the square root term on one side. Add 99 to both sides:

5x+44=33x55+99\sqrt{5x + 44} = 33x - 55 + 99

Simplify the right side:

5x+44=33x+44\sqrt{5x + 44} = 33x + 44

Step 2: Square both sides to eliminate the square root.

(5x+44)2=(33x+44)2(\sqrt{5x + 44})^2 = (33x + 44)^2

This gives:

5x+44=(33x+44)25x + 44 = (33x + 44)^2

Step 3: Expand the right side.

Now expand (33x+44)2(33x + 44)^2:

(33x+44)2=33x×33x+2×33x×44+44×44(33x + 44)^2 = 33x \times 33x + 2 \times 33x \times 44 + 44 \times 44 =1089x2+2904x+1936= 1089x^2 + 2904x + 1936

Now the equation is:

5x+44=1089x2+2904x+19365x + 44 = 1089x^2 + 2904x + 1936

Step 4: Move all terms to one side.

Subtract 5x+445x + 44 from both sides:

0=1089x2+2904x+19365x440 = 1089x^2 + 2904x + 1936 - 5x - 44

Simplify:

0=1089x2+2899x+18920 = 1089x^2 + 2899x + 1892

Step 5: Solve the quadratic equation.

Now we solve the quadratic equation:

1089x2+2899x+1892=01089x^2 + 2899x + 1892 = 0

We can apply the quadratic formula:

x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Where:

  • a=1089a = 1089
  • b=2899b = 2899
  • c=1892c = 1892

Now, let's compute the solution.The solutions to the quadratic equation are:

x11.146andx21.516x_1 \approx -1.146 \quad \text{and} \quad x_2 \approx -1.516

Both are valid solutions as the discriminant (162649162649) is positive.
