Questions: Simplify. #6) (X^2+4X-5)/(X^2+3X-10) * (X+3)/(X^2+2X-3)

Solution Steps

To simplify the given expression, we need to factor each polynomial in the numerators and denominators. After factoring, we can cancel out any common factors between the numerators and denominators.

We start with the expression:

\[ \frac{X^{2}+4X-5}{X^{2}+3X-10} \cdot \frac{X+3}{X^{2}+2X-3} \]

Factoring each part, we find:

• \( X^{2}+4X-5 = (X - 1)(X + 5) \)
• \( X^{2}+3X-10 = (X - 2)(X + 5) \)
• \( X + 3 \) remains as is.
• \( X^{2}+2X-3 = (X - 1)(X + 3) \)

Substituting the factored forms back into the expression gives us:

\[ \frac{(X - 1)(X + 5)}{(X - 2)(X + 5)} \cdot \frac{X + 3}{(X - 1)(X + 3)} \]

Next, we can cancel the common factors in the numerator and denominator:

• The factor \( (X + 5) \) cancels.
• The factor \( (X - 1) \) cancels.
• The factor \( (X + 3) \) cancels.

This simplifies our expression to:

\[ \frac{1}{X - 2} \]
