Answer 1

Answer:

u should use here formula of a+b....a-b

Answer 2

Answer:

x^2 + (a/(a+b) + (a+b)/a)x + 1 = 0

multiplying the equation with a(a+b) both side

a(a+b)x^2 + (a^2 + (a+b)^2)x + a(a+b) = 0

a(a+b)x^2 + a^2x + (a+b)^2x + a(a+b) = 0

ax((a+b)x + a) + (a+b)((a+b)x + a) = 0

(ax + a+ b)((a+b)x + a) = 0

hence, either

ax + a + b = 0 which gives

x = - (a + b)/a

or

(a+b)x + a= 0 which gives

x = - a/(a+b)
