Answer:
Option A
Step-by-step explanation:
We can try to factorize all the options one by one.
For A:
We can see that the quadratic expression cannot be solved by factorization as the factors at the end of factorization are not equal in both brackets. So Option A is the correct answer for the given question.
Moreover we can also note that all the other quadratic expressions can be factorized ..

B. 57⁄90, rational
C. 63⁄90, rational
D. 63⁄99, rational
answer B
We assume x= 0.6333
100x = 63.3333
10x= 6.333 33 (subtract it )
----------------------------
90x = 57 ( divide by 90 on both sides)
So x=
Answer :
When we can write a number in fraction form then it is a rational number.
We converted the decimal number into a fraction so it is rational
The answer is B. 57/90, rational.
