Simplify and State Restrictions: 2/(x^2+7x+12) + 5/(x^2+5x+6)?
My answer is as follows:
2/(x+3)(x+4) + 5/(x+2)(x+3)
= (2(x+3)(x+2))/((x+2)(x+3)(x+4)) + (5(x+3)(x+4))/((x+2)(x+3)(x+4))
= (2(x^2+2x+3x+6))/((x+2)(x+3)(x+4))+(5(x^2+4x+3x+12))/(x+2)(x+3)(x+4)
= (2x^2+10x+12)/((x+2)(x+3)(x+4)) + ((5x^2+35x+60)/(x+2)(x+3)(x+4))
Final Answer being:
(7x^2+45x+72) / ((x+2)(x+3)(x+4))
Restrictions are: x cannot be -2, -3, -4
Am I Right?
Thanks in Advance!
