Solved by the complete square method a²x²-3abx+2b²=0 |
| Answer» The given equation is:a2x2\xa0- 3abx + 2b2 = 0{tex}\\Rightarrow{/tex}\xa0a2x2\xa0- 3abx = -2b2Adding\xa0{tex}\\left( \\frac { 3 b } { 2 } \\right) ^ { 2 }{/tex} on both sides, we have,{tex}(ax)^2-2\\times(ax)\\times\\frac{3b}2+\\left(\\frac{3b}2\\right)^2=-2b^2+\\left(\\frac{3b}2\\right)^2{/tex}{tex}(ax-\\frac{3b}2)^2=-2b^2+(\\frac{3b}2)^2{/tex}{tex}(ax-\\frac{3b}2)^2=\\frac{b^2}4{/tex}\xa0{tex}\\Rightarrow \\quad \\left( a x - \\frac { 3 b } { 2 } \\right) = \\pm \\frac { b } { 2 }{/tex}\xa0(By taking square root on both sides)So either,\xa0{tex} \\left( a x - \\frac { 3 b } { 2 } \\right) = \\frac { b } { 2 }{/tex}\xa0or\xa0{tex}\\left( a x - \\frac { 3 b } { 2 } \\right) = \\frac { - b } { 2 }{/tex}{tex}\\Rightarrow \\quad a x = \\left( \\frac { b } { 2 } + \\frac { 3 b } { 2 } \\right) = \\frac { 4 b } { 2 }{/tex}= 2b,thus,\xa0x = 2b/aor ax =\xa0{tex}\\left( \\frac { - b } { 2 } + \\frac { 3 b } { 2 } \\right) = \\frac { 2 b } { 2 }{/tex}\xa0= bthus, x = b/aSo,\xa0x =\xa0{tex}\\frac { 2 b } { a }{/tex}\xa0or x =\xa0{tex}\\frac { b } { a }{/tex}.Hence,\xa0the roots of the given equation are\xa0{tex}\\frac { 2 b } { a }{/tex}\xa0and\xa0{tex}\\frac { b } { a }{/tex}. | |

if tan a 3/4 then prove that sinA cosA 12/25 |
| Answer» Given, tan A =\xa0{tex}\\frac { 3 } { 4 }{/tex}⇒ tan A =\xa0{tex}\\frac { P } { B } = \\frac { 3 x } { 4 x }{/tex}\xa0[ from figure ]H2\xa0= P2\xa0+ B2\xa0[By Pythagoras theorem]= (3x)2\xa0+ (4x)2= 9x2\xa0+ 16x2⇒ H2\xa0= 25x2or, H2=(5x)2⇒ H = 5xTherefore,sin A =\xa0{tex}\\frac { P } { H } = \\frac { 3 x } { 5 x } = \\frac { 3 } { 5 }{/tex}and cos A =\xa0{tex}\\frac { B } { H } = \\frac { 4 x } { 5 x } = \\frac { 4 } { 5 }{/tex}Now, LHS = sin A cos A\xa0{tex}= \\frac { 3 } { 5 } \\times \\frac { 4 } { 5 } = \\frac { 12 } { 25 }{/tex} = RHSHence, proved. | |

For any positive integer x prove that there exists an irrational no. y such that 0 |
| Answer» If x is irrational, then {tex}y = \\frac { x } { 2 }{/tex} is also an irrational number such that 0 < y < x.If x is rational, then\xa0{tex}\\frac { x } { \\sqrt { 2 } }{/tex}\xa0is an irrational number such that\xa0{tex}\\frac { x } { \\sqrt { 2 } } < x{/tex}\xa0as\xa0{tex}\\sqrt { 2 } > 1{/tex}.{tex}\\therefore \\quad y = \\frac { x } { \\sqrt { 2 } }{/tex}\xa0is an irrational number such that 0 < y < x.Hence, for any positive real number x, there exists an irrational number y such that 0 < y < x. | |
