Add the following expressions:3z^(3)-z^(2)+5, 1-2z+z^(2), 3+2z-z^(3) | 7 | ALGEBRAIC EXPRESSION...

Add the following: (i) x – 3y – 2z , 5x + 7y – 8z , 3x – 2y + 5z

Evaluate each of the following algebraic expressions for x=2,\ y=-3,\ z=-2,\ a=2,\ b=3: (i) ax+by+z

The value of the expression ((x ^(2) - y ^(2)) ^(3) + ( y ^(2) - z ^(2)) ^(3) + (z ^(2) - x ^(2)) ^(3))/((x - y) ^(3) + ( y - z) ^(3) + (z - x ) ^(3)) is

Given z_(1)+3z_(2)-4z_(3)=0 then z_(1),z_(2),z_(3) are

On the Argand plane ,let z_(1) = - 2+ 3z,z_(2)= - 2-3z and |z| = 1 . Then

Let z_(1), z_(2), z_(3) be the roots of iz^(3) + 5z^(2) - z + 5i = 0 , then |z_(1)| + |z_(2)| + |z_(3)| = _____________.

If |z_(1)|=2,|z_(2)|=3,|z_(3)|=4 and |2z_(1)+3z_(2)+4z_(3)|=4 then the expression |8z_(2)z_(3)+27z_(3)z_(1)+64z_(1)z_(2)| equals (A) 72 (B) 24(C)96(D)92

If z=(1)/(2)(i sqrt(3)-1), then find the value of (z-z^(2)+2z^(3))(2-z+z^(2))
