Question 8. Asked on :09 June 2022:11:09:09 AM

If the 1st term of a series is 7 and 13th term is 35. find the sum of 13 terms of the sequence.

-Added by Master Purushottam Mathematics » Arithmetic Progressions

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.

Question 9. Asked on :09 June 2022:10:56:24 AM

Value of the roots of the quadratic equation,

x-x-+=0 are.................

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

-Added by Master Purushottam Mathematics » Algebra Expression

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
