Question

5x÷2x -1 = 2
solve it
​

Answer 1

Answer:

Set up the long division

 

x =   x2

x .

Choose x since

x · x matches x2.

x2 + 2x = x(x + 2).

Subtract x2 + 2x from x2 + 5x + 9.

Result is 3x + 9.

 

3 =   3x

x .

Choose 3 since

3 · x matches 3x.

3x + 6 = 3(x + 2).

Subtract 3x + 6 from 3x + 9.

Result is 3.

3 is the remainder.
