Given:
[tex]\frac{x^2y^4}{x^2+11x+28}\cdot\frac{x^2+2x-8}{x^6y^3}[/tex]Step 1
Factor the denominator of the first fraction and the numerator of the second fraction.
[tex]\frac{x^2y^4}{(x+4)(x+7)^{}}\cdot\frac{\mleft(x+4\mright)(x-2)}{x^6y^3}[/tex]Step 2
Multiply
[tex]\frac{x^2y^4}{\mleft(x+7\mright)(x+4)^{}}\cdot\frac{\mleft(x+4\mright)(x-2)}{x^6y^3}=\frac{x^2y^4(x+4)(x-2)}{(x+7)(x+4)x^6y^3^{}}[/tex]
