Question

If fourteen is added to the square of a number, the result is seventy-eight. Find all such numbers.

If there is more than one answer, separate them with the "and" button.
If there is no such number, select the "None" button.

Answer 1

Explanation:

Subtracting 14 from both sides of the equation, we get:

x^2 = 64

Taking the square root of both sides, we get:

x = ±8

Therefore, the two numbers are 8 and -8.
