Question

The square of a number is equal to 16 less than eight times the number

Answer 1

Answer: 4

Explanation:

Let's assume the number is 'x'. From the given statement, we can write the equation:

x^2 = 8x - 16

To solve for x, we can rearrange the equation and bring all the terms to one side:

x^2 - 8x + 16 = 0

We can factor this quadratic equation as follows:

(x - 4)^2 = 0

This gives us only one solution for x, which is:

x = 4

Therefore, the number is 4.
