Answer» ANSWER: This implies that x2+2ax=4x−4a−13 or x2+2ax−4x+4a+13=0 or x2+(2a−4)x+(4a+13)=0 Since the equation has just one solution instead of the usual two distinct solutions, then the two solutions MUST be same i.e. DISCRIMINANT = 0. Hence we GET that (2a−4)2=4⋅1⋅(4a+13) or 4a2−16a+16=16a+52 or 4a2−32a−36=0 or a2−8a−9=0 or (a−9)(a+1)=0 So the values of a are −1 and 9.

Answer»

ANSWER:

This implies that

x2+2ax=4x−4a−13

or

x2+2ax−4x+4a+13=0

or

x2+(2a−4)x+(4a+13)=0

Since the equation has just one solution instead of the usual two distinct solutions, then the two solutions MUST be same i.e. DISCRIMINANT = 0.

Hence we GET that

(2a−4)2=4⋅1⋅(4a+13)

or

4a2−16a+16=16a+52

or

4a2−32a−36=0

or

a2−8a−9=0

or

(a−9)(a+1)=0

So the values of a are −1 and 9.

Answer»

Hey MATE

Step-by-step explanation:

xi = 5000 , 6000 , 7500 , 9000

fi = 4 , 5 ,. 4 ,. 2

xifi = 20000 , 30000 , 30000 , 18000

Mean = Σxifi / Σfi {Σfixi = 98000 , Σfi = 15 }

= 98000 / 15

= 6533.34

Σ = sigma which MEANS summation..

PLEASE mark as BRAINLIEST !!!!!
