Question

Two positive integers have a product of 176. One integer is 5 less than the other integer. Which equation can be used to find the value of x, the greater integer?

Answer 1

$xy=176$
$y=x-5$

$\implies x(x-5)=176\implies x^2-5x-176=(x+11)(x-16)=0$
$\implies x=-11, x=16$

Since $x>0$, we take $x=16$, which means $y=16-5=11$.

Answer 2

Answer: X(X-5)=176
