Answer 1

Answer:

CHEMISTRY

A solution is defined as a:

A .

Homogeneous mixture of two or more substances

Heterogeneous mixture of two or more substances

C .

Homogeneous mixture of liquid and solid components only

D .

Homogeneous mixture consisting of water as one of the components

A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase. 

A solution consists of a solute and a solvent. 

The solute is the substance that is dissolved in the solvent.

For example, in a saline solution, salt is the solute dissolved in water as the solvent.

Step-by-step explanation:

If a and b are the roots of quadratic equation (x-2)(x - 3) + (x - 3)(x + 1)+ (x + 1) (x - 2) = 0,

then the value of -

[(a +1)(b+1)]^-1 [(a-2)(b-2)]^-1 [(a - 3)(b-3)]^-1

(B)-1
