Question

if the sum of a number and it's Positive square root is 56 find the number​

Answer 1

Answer:

Therefore x= -8, and x = 7.

Step-by-step explanation:

Let's set up the problem like this:

 

1. x + x2 = 56

2. Subtract 56 from both sides leaves us x +x2 -56 =0; rearranging gives us x2+x-56=0  

3. Note that the equation in step 2 is a quadratic equation.

4. Factoring the equation gives us (x+8)*(x-7) = 0

5. Therefore x= -8, and x = 7.
