" 19."x^(2)-26x+153

Prove that : 2x^(4) - 9x^(3) + 21x^(2) - 26x + 12 is completely divisible by 2x - 3.

If 3 - sqrt(2) is a root of x^(4) - 8x^(3) + 21x^(2) - 26x + 14 = 0 then the roots are

If tan "" (alpha )/(2) and tan "" (beta)/( 2) are the roots of the equation 8x ^(2) -26x + 15 =0, then find the value of cos (alpha + beta).

If tan "" (alpha )/(2) and tan "" (beta)/( 2) are the roots of the equation 8x ^(2) -26x + 15 =0, then find the value of cos (alpha + beta).

One of the dimensions of the cuboid whose volume is 16x^(2)-26x+10 is

If tan""(alpha)/(2)andtan""(beta)/(2) are roots of the equation 8x^(2)-26x+15=0 then cos(alpha+beta) = …………

If tan((alpha)/(2)) and tan (( beta)/(2)) are the roots of the equation 8x^(2)-26x+15=0 then cos (alpha+ beta)=

If tan((alpha)/(2)) and (tan beta)/(2) are the roots of the equation 8x^(2)-26x+15=0 then the cos(alpha+beta) is equal to
