AAAaannndd the bot gets it wrong yet again!
Start Fraction 5 over t squared End Fraction minus Start Fraction 4 over t plus 1 End Fraction
5/t^2 - 4/(t+1)
= (5(t+1) - 4t^2)/(t^2(t+1))
= (-4t^2+5t+5)/(t^2(t+1))
so D
Start Fraction 5 over t squared End Fraction minus Start Fraction 4 over t plus 1 End Fraction
5/t^2 - 4/(t+1)
= (5(t+1) - 4t^2)/(t^2(t+1))
= (-4t^2+5t+5)/(t^2(t+1))
so D
. start fraction 5 + 5 t - 4 t squared over t squared times left parenthesis t + 1 right parenthesis end fraction is the correct answer. Thank you for catching the mistake!
