Consider 8x2 - 48x = -104.
ki77a [65]

Answer:

3+ 2\mathbf{i}

3- 2\mathbf{i}

Step-by-step explanation:

<u>Quadratic Equation Solving</u>

We have the equation:

8x^2-48x=-104

Divide by 8:

x^2-6x=-13

Now complete the squares so the left side is a perfect square of a binomial:

x^2-6x+9=-13+9=-4

Factoring the perfect square:

(x-3)^2=-4

Taking the square root:

x-3=\sqrt{-4}

The square root of a negative number is an imaginary number:

x-3=\pm 2\mathbf{i}

Solving for x:

x=3\pm 2\mathbf{i}

The solutions are:

3+ 2\mathbf{i}

3- 2\mathbf{i}

mart [117]

The simplified expression for the area of the rectangular table is Three-halves x squared, 3x²/2

<h3>What is the area of the rectangular table?</h3>

Since the carpenter built a square table with side length x.  Next, he will build a rectangular table by tripling one side and halving the other.

To find the area of the rectangular table, we know that Area, A = LW where

  • L = length and
  • W = width

Now, since the length of the square is x, and the rectangular table has one side of the square tripled and halving the other side .

So,

let

  • length of the rectangular table = L = x/2 and
  • width of rectangular = W = 3x

So, the area of the rectangular table A = LW

= x/2 × 3x

= 3x²/2

So, the simplified expression for the area of the rectangular table is Three-halves x squared, 3x²/2
