i asked this question 3 days ago, im just going to give up. sometimes there are people that just post the steps and its easy to compare what i did wrong with the correct steps, i guess their not coming here.
Well i don't know why you give up or why you don't understand it.
Just follow these rules.
a)To add 2 or more fractions they must have the same denominator.
b)If you multiply with the same non-zero number the numerator and the denominator the value of the fraction remains the same.
Simple as that.
So does not have the same denominator.
So we should just make it have(in order rule a) to be true).
How? With the help of rule b).
So we multiply with t both the numerator and denominator.
And also we multiply with t-6 both the numerator and denominator.
After we do this, we add the numerators to get the new single numerator of our new fractions and the final single fraction has the same denominator.
