Answer:
75x - 36 = x²
Step-by-step explanation:
let x be the integer
75x - 36 = x²
More or less, translate each section of the problem in word form into algebraic form.
"Seventy five times an integer" is 75x
"minus 36" is -36
"equals the square of the integer" is = x²
To solve:
Since 75x - 36 = x² is a quadratic, use the quadratic formula.
Rearrange so that all terms are on one side.
This is called standard form (ax² + bx + c = 0)
75x - 36 = x²
0 = x² - 75x + 36
a = 1 b= -75 c=36
[tex]x = \frac{-b ±\sqrt{b^{2}- 4ac} }{2a}[/tex] (ignore that weird A)
Substitute a, b and c into the quadratic formula to solve for x, the integer.
