Write the condition for the roots of the equation (a2+b2)x2 -2b(a+c)x + (b2+c2)=0 to be equal |
| Answer» We have the following equation,{tex}(a^2+b^2)x^2-2b(a+c)x+(b^2+c^2)=0{/tex}Since equation\xa0has\xa0equal roots,D = 0{tex}\\Rightarrow{/tex}\xa0B2\xa0- 4AC\xa0= 0{tex}\\Rightarrow{/tex}\xa0[-(2ab + 2bc)]2\xa0- 4(a2 + b2)(b2 +c2) = 0{tex}\\Rightarrow{/tex}\xa0[4a2b2\xa0+ 4b2c2\xa0+ 8ab2c] - 4[a2b2\xa0+ a2c2\xa0+ b4\xa0+ b2c2] = 0{tex}\\Rightarrow{/tex}\xa0[4a2b2\xa0+ 4b2c2\xa0+ 8ab2c] -4a2b2\xa0-4a2c2\xa0-4b4\xa0- 4b2c2 = 0{tex}\\Rightarrow{/tex}\xa0-4b4\xa0-4a2c2\xa0+ 8ab2c = 0\xa0{tex}\\Rightarrow{/tex}\xa0-4(b4\xa0+\xa0a2c2\xa0-2ab2c) = 0{tex}\\Rightarrow{/tex}\xa0b4\xa0+ a2c2\xa0- 2ab2c = 0\xa0{tex}\\Rightarrow{/tex}\xa0(b2\xa0- ac)2\xa0= 0\xa0{tex}\\Rightarrow{/tex}\xa0b2\xa0- ac = 0\xa0{tex}\\Rightarrow{/tex}\xa0b2 = ac | |

p, q, r the term of A.P. are a, b, c then prove that a(q-r)+b(r-p)+c(p-q) =0 |
| Answer» Let the first term and common difference of the AP be A and Dpth term = a ……… (given)= A + (p – 1)D = a\xa0............(1)qth term = b{tex}\\Rightarrow {/tex}\xa0A + (q - 1) D = b ......... (2)rth term = c .......... Given{tex}\\Rightarrow {/tex}\xa0A + (r - 1) D = c ........ (3)Multiplying equations (1), (2) and (3) by q - r, r - p and p - q respecitvely, we geta(q - r) + b(r - p) + c(p - q)= [A + (p - 1) D] (q - r) + [A + (q - 1)D] (r - p) + [A + (r - 1) D] (p - q)]= A [q - r + r - p + p - q] + D [(p - q)\xa0(q - r) + (q\xa0- 1) (r- p) + (r - 1) (p - q)]= A (0) + D(0)= 0 | |
