Question

When 36 is subtracted from the square of a number, the result is five times the number. What is the positive solution?

Answer 1

9

Explanation:

`x^(2)` - 36 = 5x

`x^(2)` - 36 = 5x

`x^(2)` -5x = 36

`9^(2)` - 45 = 36

+ 45 + 45

-----------------------

81 = 81 ✅

`9^(2)` - 36 = 5(9)

81 - 36 = 45 ✅
