Question

The equation 24x2+25x−47 ax−2 =−8x−3− 53 ax−2 is true for all values of x≠ 2 a , where a is a constant

Answer 1

Answer :

24x2+ 25x − 47 divided by ax − 2 is equal to

−8x −3 with remainder −53,

it is true that (−8x − 3)(ax − 2) − 53 = 24x2 +25x −47.

(This can be seen by multiplying each side of the given equation by ax − 2).

This can be rewritten as −8ax2+ 16x − 3ax = 24x2+ 25x − 47.

Since

the coefficients of the x2

-term have to be equal on both sides of the equation,

−8a = 24, or a = −3.
