(x = 5 ), (x = - 2 )

Explanation:

when 10 is subtracted from the square of a number the result is 3 times the number.

Find the positive solution.

Let: x = number

Let x^2 = square of a number.

x^2 - 10x = 3x transpose

x^2 - 3x - 10 = 0

Apply Factoring: Fractions of 10 are 5 and 2

( - 5)(2) = - 10

- 5 + 2 = - 3

( x - 5 )(x + 2) = 0

x - 5 = 0 x + 2 = 0

x = 5 x = - 2

So the positive solution is:

ANSWER: X = 5

I hope that helps!!!!
