Q. Perform the following operation and express in simplest form.\newlinex236x26xx2x2+2x24 \frac{x^{2}-36}{x^{2}-6 x} \cdot \frac{x^{2}}{x^{2}+2 x-24} \newlineAnswer:
  1. Identify Factors: Identify the factors of the numerator and denominator in each fraction to simplify the expression.\newline(x236)(x^2 - 36) can be factored as (x+6)(x6)(x + 6)(x - 6) because it is a difference of squares.\newline(x26x)(x^2 - 6x) can be factored as x(x6)x(x - 6) by taking out the common factor xx.\newline(x2+2x24)(x^2 + 2x - 24) can be factored as (x+6)(x4)(x + 6)(x - 4) by finding two numbers that multiply to 24-24 and add to 22.
  2. Rewrite with Factored Forms: Rewrite the original expression with the factored forms. [(x+6)(x6)x(x6)×x2(x+6)(x4)][\frac{(x + 6)(x - 6)}{x(x - 6)} \times \frac{x^2}{(x + 6)(x - 4)}]
  3. Cancel Common Factors: Cancel out the common factors from the numerator and denominator.\newlineThe (x6)(x - 6) terms cancel out, and one (x+6)(x + 6) term cancels out.\newlineWe are left with:\newline1x×x2(x4)\frac{1}{x} \times \frac{x^2}{(x - 4)}
  4. Simplify Remaining Expression: Simplify the remaining expression.\newlineThe xx in the denominator and one xx from x2x^2 in the numerator cancel out.\newlineWe are left with:\newlinexx4\frac{x}{x - 4}
  5. Check for Further Simplification: Check for any further simplification. Since xx cannot be factored further and there are no common factors left, the expression is now in its simplest form.
