_ x ( x^2+5 x-7 -x )=

Options

A7 2
B5
C5 2
D6

Correct answer

C. 5 2

Step-by-step solution

aligned & _ x x^2+5-7 -x & = _ x ( x^2+5 x-7 ) ( x^2+5 x-7+x ) ( x^2+5 x-7+x ) & = _ x x^2+5 x-7-x^2 ( x^2+5 x-7+x ) aligned Dividing numerator and denominator by x , we get = _ x 5- 7 x ( 1+ 5 x - 7 x^2 +1 ) = 5 1 +1 = 5 2
