Answer:

Step-by-step explanation:
(x - 1) ×
( cancel the factor (x - 1) on numerator and denominator
= 1
[ In the same way 2 ×
= 1 ]
The required rational expression is 
Round each number to the nearest 10.
33 rounds to 30 and 89 rounds to 90, thus in your head it's easier to mentally add 30 + 90 for purposes of estimation.
3+2= 5
You have 3 and add 2 and get 5
Mark brainliest please
Answer:
(x-5)(x+1)
Step-by-step explanation:
Since the highest power of x is 2, u can assume the equation to be (x +/- A) (x +/- B), whereby A and B are unknowns.
Since the coefficient of X^2 is 1, and the number in the equation is - 5, the only possible values for A and B to get - 5 is either - 5 and 1 or 1 and - 5.
Since coefficient of x is - 4 and number in equation is - 5, imagine inserting those numbers in the equation and cross multiplying back. You would realise that the answer should be as listed above.
