Question

What is the quotient? x + 5 )divided by 4x2 + 14x − 9 a) 4x + 6 + 21/x+5 b) 4x + 6 − 39/x+5 c) 4x − 6 + 21/x+5 d) 4x − 6 − 39/x+5

Answer 1

C...................

Answer 2

`(4x - 6) + (21)/(x+5)`

Explanation:

4x^2 +14x -9 divide by x+5

4x - 6 (quotient)

--------------------------------

x+5 4x^2 +14x - 9

4x^2 +20x

--------------------------- (subtract it )

-6x -9

-6x -30

----------------------------(subtract)

+21 (Remainder)

`(4x - 6) + (21)/(x+5)`
