We will use the Descartes` rule of signs and see how many times the signs change from positive to negative and from negative to positive from one term to the next ( two consecutive terms are with different signs ).
In this case it is 4 times ( +7x13 to -12x9, -12x9 to +16x5, +6x5 to -23 x and finally -23x to +42 ).
Answer: There are 4 real zeroes.
Answer:
Uncontrolled cell division can lead to the formation of masses of cells that can remain in a place called <u>primary </u>tumors or ones that can move called <u>metastatic </u>tumors.
Explanation:
The term primary tumor refers to the original tumor, a place where the tumor first appeared.
Metastatic tumors are tumors that appear in other organs and originate from the primary tumor. Tumor cells can break away from the primary tumor and travel to other locations in the body through the blood or lymph system and form new tumors. This is how metastatic tumors appear.
For example, a brain tumor is a primary tumor if it first appeared in the brain. A metastatic brain tumor is a tumor that appeared in another organ and then spread to the brain.

<h3>What is Blood Transfusion?</h3>
Intravenously putting blood components into a person's circulation is known as a blood transfusion. For a number of medical disorders, transfusions are performed to replenish lost blood components. The blood's components, such as red blood cells, white blood cells, plasma, clotting factors, and platelets, are now frequently used in transfusions instead of the whole blood that was used in earlier times.
Hemoglobin is a component of red blood cells (RBC), which carry oxygen to the body's cells. Although they are not frequently utilized in transfusions, white blood cells are an essential component of the immune system and help the body fight illnesses. The "yellowish" liquid component of blood called plasma serves as a lubricant and is made up of essential nutrients and proteins for the body's overall health.
