the square of a positive number subtracted by 5 times the number is equal to 50
set up an equation and solve to find the number
:
x^2 - 5x = 50
Form a quadratic equation
x^2 - 5x - 50 = 0
Factors to
(x-10)(x+5) = 0
Two solutions
x = 10, -5
:
:
See if that checks out
10^2 - 5(10) = 50
and
-5^2 - 5(-5) = 50
25 + 25 = 50
