-Added by Master Purushottam Mathematics » Arithmetic Progressions

Answer:

 a= 7 , a13 = 35 
   

Sn = n2 (a + l)

S13 = 132 (7+35)

      = 132 x 42

      = 13 x 21 

      = 273

Hence, the sum of the first 13 term of the sequence is 273.

-Added by Master Purushottam Mathematics » Quadratic Equations

Answer:

 CORRECT EQUALTION 

x-x- 2 =0 

=> x - x - 6 =0

=> x-3x + 2x - 6 =0

=> x(x-3) + 2(x-3) = 0

=> (x - 3) (x+2) = 0

=> x = 3 , x = -2

Question 10. Asked on :09 June 2022:10:42:27 AM

 solve for x (in term of a and b):

a/x-b + b/x-a = 2, x≠ a,b

See All Answers

-Added by Master Purushottam Mathematics » Algebra Expression

Answer:

 a(x-a) + b(x-b) 
(x-b) (x-a)
 = 2

cross multiplying both the sides 

a(x-a) + b(x-b) = 2[x2-(a+b)x+ ab]

ax- a2 + bx -b2  = 2x2 -2(a+b)x + 2ab

2x2 -3(a+b)x + (a+b)2 = 0 

2x2 -2(a+b)x -(a+b)x + (a+b)2 = 0

[2x- (a+b) ] [x-(a+b)] = 0

        

x = a + b, a + b2
