1.

If a,b,c are rational then the root of equation (a+2b-3c )x²+(b+2c-3a)x+ (c+2a-3b)=0

Answer»

$\textbf{Given:}$

$(a+2b-3c)x^2+(b+2c-3a)x+(c+2a-3b)=0$

$\textbf{To find:}$

$\text{Roots of the equation}$

$\textbf{Solution:}$

$\text{Consider,}$

$(a+2b-3c)x^2+(b+2c-3a)x+(c+2a-3b)=0$

$\text{Sum of the coefficients=}(a+2b-3c)+(b+2c-3a)+(c+2a-3b)$

$=0$

$\therefore\text{(x-1) is a factor}$

$\textbf{By synthetic division}$

$\begin{array}{r|ccc}1&a+2b-3c&b+2c-3a&c+2a-3b\\&&a+2b-3c&-c+3b-2a\\\cline{2-4}&a+2b-3c&-2a+3b-c&|0\end{array}$

$\text{Quotient=}(a+2b-3c)x+(-2a+3b-c)$

$(a+2b-3c)x+(-2a+3b-c)=0$

$\implies\,x=\dfrac{c+2a-3b}{a+2b-3c}$

$\therefore\textbf{The roots are $1$ and $\dfrac{c+2a-3b}{a+2b-3c}$}$

Find more:

If alpha,beta are the roots of equation x^2-5x+6=0 and alpha > beta then the equation with the roots (alpha+beta)and (alpha-beta) is

Answer» Hiiiii dear_______✌️✌️✌️✌️✌️ Given ratio of sum of n terms of two AP’s = (2n+1):(2n+5) Let’s consider the ratio these two AP’s 10th terms as A10 : a’10 →(2) Recall the 10th term of AP formula, an = a + 9d Hence EQUATION (2) becomes, a10 : a’10 = a + 9d : a’ + 9d’ On MULTIPLYING by 2, we get a10 : a’10 = [2a + 29d] : [2a’ + 29d’] = [2a + 18D] : [2a’ + 18d’] =( S2) 10th – 1 : (S’2) 10th – 1 = [2(10 )+ 1] : [2(10 )+5] [from (1)] = 21 : 25 Thus the ratio of 10th terms of two AP’s is 21:25

Answer» P will COMPLETE whole WORK in 12 days R will complete in 18 days A in 10 days 1 day work of P R A = 1/12 + 1/18 + 1/10 = 1/180 they WORKED for 3 days together, so 3 days work = 3/180 = 1/60 So 1/60 work is complete and remaining is 59/60 that has to be COMPLETED by R So 59*18 / 60 = 17.7 days

41.

p takes 4 days to complete 1/3rd of a job r takes 3 days to complete 1/6th of the same work and a takes 5 days to complete half the job.if all of them work together for 3 days and p and a quit how long will it take for r to complete the remaining work done.

Answer»

P will COMPLETE whole WORK in 12 days

R will complete in 18 days

A in 10 days

1 day work of P R A = 1/12 + 1/18 + 1/10 = 1/180

they WORKED for 3 days together, so 3 days work = 3/180 = 1/60

So 1/60 work is complete and remaining is 59/60

that has to be COMPLETED by R So 59*18 / 60

= 17.7 days
