Its weird because I get the ones with vairables, but these which most of the time would seem easier, just doesnt click and for me seems to take 10 times more time/ effort then the ones with variables.

\[\Large \frac{x^{2}3x54}{x^{2}18x+81}*\frac{x^{2}+12x+36}{x+6}\] Step 1. Factor the first numerator. Step 2. Factor the first denominator. Step 3. Factor the second numerator. Keep in mind: \[\Large x^{2}+(a+b)x+(a*b)\] In otherwords, what two numbers when added together get you the middle number, and when multiplied get you the last one? Example: Step 1: 6+9=3 6*(9) = 54 Therefore step 1 = (x+6)(x9)

(x2 3x 54) / (x2 18x + 81) * (x2 +12x +36) / (x+6) x2 3x 54 = x2 9x +6x 54 = x(x9) +6 (x9) = (x  9) (x +6) x2 18x + 81= x2 9x 9x + 81 = (x  9) (x 9) x2 +12x +36 = x2 +6x +6x +36 = (x +6) ( x +6) Now substituteall this values in equation.. dw:1341903760054:dw
