" (iii) "x^(2)-22x+105=0" समीकर्णों का मूल "alpha" एवं "beta" होने से "(alpha-beta)" का मास लिखें। "

If the roots of the equation x^(2)-22x+105=0 be alphaandbeta , then find the value of (alpha-beta) .

If the roots of x ^(4) -10 x ^(3) + 37 x ^(2) - 60 x + 36 =0 are alpha, alpha , beta, beta (alpha lt beta), then 2 alpha + 3 beta - 2 alpha beta=

IF alpha , beta are the roots of x^(2)-x+2=0 then alpha ^ 2 beta + alpha beta ^2 =

If alpha,beta " are the roots of the equation "x^(2) - 2x - 1 =0, "then what is the value of " alpha^(2)beta^(-2)+alpha^(-2)beta^(2)

If alpha+beta=90^@ , and alpha=2 beta , then the value of 3 cos^2 alpha-2 sin^2 beta is: यदि alpha+beta=90^@ , और alpha=2 beta , तो 3 cos^2 alpha-2 sin^2 beta का मान ज्ञात करें:

IF alpha , beta are the roots of x^2 - ax +b=0 , then the whose roots are (alpha + beta ) /( alpha ) , (alpha + beta)/( beta) is
