Fill in the blank, when:
x = 3, y = 6, z = 18, a = 2, b = 8, c = 32 and d = 0.

a + b + x = ...................

If a = 3, b = 0, c = 2 and d = 1, find the value of a² + 2b² − 3c²

Show that the value of x³ – 8x² + 12x – 5 is zero, when x = 1.

If m = 2, find the difference between the values of 4m³ and 3m⁴.

Simplify:

− (− 4a − 8a)

If x = 2, y = 3 and z = 4, find the value of 3x² – 4y² + 2z².

If x = 3, y = 2 and z = 1; find the value of y² – x² + 6z²

Multiply and then evaluate:

(x – 2y + z) and (x – 3z); when x = − 2, y = − 1 and z = 1.

Simplify:

`8"x"−(3"x"−overline(2"x"-3))`

If x = − 3, find the value of 2x³ + 8x² – 15.
