The product of two numbers is x2+x−2. If one of the numbers is x−1, Then the other number is
x−2
x+2
x+1
x−1
The the other number be y.
Then, we must have, (x−1)×y = x2+x−2
⟹ y = x2+x−2x−1
We perform division as follows.
Hence y = x+2.
The product of two numbers is x2+3x−54. If one number is x−6, then the other number is ____.
If x = √2+√1, then the value of [x+1x] is ?
If one number is x and other number is 3 more than one third of first number, then the other number is
