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

Answer:

9

Step-by-step 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 ✅
