If 5 is added to the square of a number, the result is eighty six

Answer 1

Hi Gage,

I assume that you are supposed to write an equation to represent this problem and solve the equation you make.

The text, " 5 added to the square of a number can be represented as : x² + 5

Then create an equation using the equal sign for the word, "is": = 86

Now combine the two expressions and solve for x:

x² + 5 = 86

x² + 5 - 5 = 86 - 5

x² = 81

x = square root of 81

x = 9 or -9
