Question

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

Answer 1

Answer:

Correct option is

B

−3

Given,

ax−2

24x

2

+25x−47

=−8x−3−

ax−2

53

⇒

ax−2

24x

2

+25x−47

=

ax−2

(−8x−3)(ax−2)−53

⇒24x

2

+25x−47=(−8x−3)(ax−2)−53

⇒24x

2

+25x−47=−8ax

2

+16x−3ax+6−53

⇒24x

2

+25x−47=−8ax

2

+16x−3ax−47

⇒24x

2

+25x=−8ax

2

+(16−3a)x

⇒24=−8a

⇒a=−3
