Question

Give an example of a radical equation that has no real solutions. Explain your reasoning

hint Hint:

Rearrange the equation and then solve for x.

The correct answer is: - 2

Complete step by step solution:
Here take the example to be $square root of negative x plus 7 end root equals negative 2$
Here, on squaring, we have – x + 7 = 4
⇒ x = 3
But on substituting in the original equation, we get $square root of negative 3 plus 7 end root equals square root of 4 equals 2 not equal to negative 2$
Hence this equation is an example.

The body surface area (BSA) of a human being is used to determine doses of medication. The formula for finding BSA is BSA = $square root of fraction numerator H cross times M over denominator 3600 end fraction end root$ ,where H is the height in centimeters and M is the mass in kilograms. A doctor calculates a particular dose of medicine for a patient whose BSA is less than 1.9. If the patient is 160 cm tall, what must the mass of the person be for the dose to be appropriate?
