Q. Simplify the expression completely if possible.\newlinex213x+405x240x \frac{x^{2}-13 x+40}{5 x^{2}-40 x} \newlineAnswer:
  1. Identify Terms to Factor: Identify the terms in the numerator and the denominator that can be factored. The numerator x213x+40x^2 - 13x + 40 is a quadratic expression that can be factored into two binomials. The denominator 5x240x5x^2 - 40x can be factored by taking out the common factor of 5x5x.
  2. Factor Numerator: Factor the numerator x213x+40x^2 - 13x + 40. To factor the quadratic expression, we look for two numbers that multiply to 4040 and add up to 13-13. These numbers are 8-8 and 5-5. So, x213x+40=(x8)(x5)x^2 - 13x + 40 = (x - 8)(x - 5).
  3. Factor Denominator: Factor the denominator 5x240x5x^2 - 40x. We can factor out the common term 5x5x, giving us 5x(x8)5x(x - 8). So, 5x240x=5x(x8)5x^2 - 40x = 5x(x - 8).
  4. Divide Factored Terms: Divide the factored numerator by the factored denominator.\newlineWe have (x8)(x5)/5x(x8)(x - 8)(x - 5) / 5x(x - 8).\newlineWe can cancel out the common factor of (x8)(x - 8) from the numerator and the denominator.
  5. Write Simplified Expression: Write the simplified expression.\newlineAfter canceling out the common factor, we are left with (x5)/5x(x - 5) / 5x.\newlineThis is the simplified form of the original expression.
