Reviews If The Mean Of X And 1 X Is M More

WebGiven mean x and x1 is M∴M= 2x+ x1⇒x+ x1=2MCube both the sides∴(x+ x1) 3=(2M) 3⇒x 3+ x 31+3(x+ x1)=8M 3⇒x 3+ x 31=8M 3−3(x+ x1)⇒x 3+ x 31=8M 3−3(2M)⇒x 3+ x. WebThe correct option is A 2 M 2 − 1 Given. the mean of x and 1 x is M. x + 1 x 2 = M ⇒ x + 1 x = 2 M Squaring on both the sides, (x + 1 x) 2 = 4 M 2 ⇒ x 2 + 1 x 2 = 4 M 2 − 2. ⇒ x 2 + 1.
