Solve for x and y ax/b - by/a = a+b , ax- by= 2ab |
| Answer» The given equations may be written as{tex}a^2x - b^2y = a^2b + ab^2{/tex} ....... (i){tex}ax - by = 2ab{/tex} ......... (ii)Multiplying (ii) by b and subtracting the result from (i),\xa0{tex}(a^2\xa0- ab)x = a^2b - ab^2{/tex}{tex}\\Rightarrow{/tex}\xa0{tex}(a^2\xa0- ab)x = b(a^2\xa0- ab){/tex}{tex}\\Rightarrow{/tex}{tex}x = b.{/tex}Putting {tex}x = b{/tex} in\xa0(ii), we get{tex}a b - b y = 2 a b {/tex}{tex}\\Rightarrow b y = - a b{/tex}{tex} \\Rightarrow y = \\frac { - a b } { b } = - a{/tex}Hence, x = b and y = -a. | |

What is the difference between zeroes and roots. ? |
|
Answer» Zero of a polynomial is a solution to the polynomial equation, P(x) = 0 but Root of a polynomial is that value of x that makes the polynomial equal to 0. Thanks sia and Raj kumar Mahato.. zeroes are the solution only for polynomial. But solutions are said to be roots if LHS=RHS means eqation. It is seen inQuadratic eqn.Thanks Mahi |

Show that 5-root3 is a irrational number |
| Answer» We will solve this by contradiction method i.e.,\xa0Assume\xa0{tex}5 - \\sqrt { 3 } = \\frac { p } { q }{/tex}\xa0be a rational number.{tex}\\therefore 5 - \\frac { p } { q } = \\sqrt { 3 }{/tex}\xa0or\xa0{tex}\\frac { 5 q - p } { q } = \\sqrt { 3 }{/tex},Since p,q are integers, therefore\xa0{tex}\\frac { 5 q - p } { q }{/tex} is a rational number, which is a contradiction,since\xa0{tex}\\sqrt 3{/tex} is an irrational number.Therefore, our supposition is wrong and hence, 5 - {tex}\\sqrt 3{/tex}\xa0is irrational. | |

X+Y=5, 2x-3y=4 solve by elimination and substitution method |
|
Answer» Thanks it really helped me By elimination methodx + y =5 ……….(1)2x –3y = 4 ………(2)Multiplying equation (1) by 2, we obtain2x + 2y = 10 ………..(3)2x –3y = 4 ………(2)Subtracting equation (2) from equation (3), we obtain5y = 6y = 6/5Substituting the value in equation (1), we obtainx = 5 - (6/5) = 19/5So our answer is x = 19/5 and y = 6/5By substitution methodx + y =5 ……….(1)subtract y both side we getx = 5 - y ……..,(4)plug the value of x in equation second we get2(5 – y ) – 3y = 4-5y = - 6y = -6/-5 = 6/5Plug the value of y in equation 4 we getx = 5 – 6/5x = 19/5 |
