Tap for more steps…
Consider the form x2+bx+c. Find a pair of integers whose product is c and whose sum is b. In this case, whose product is 75 and whose sum is 20.
5,15
Write the factored form using these integers.
(n+5)(n+15)=0
(n+5)(n+15)=0
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
n+5=0
n+15=0
Set the first factor equal to 0 and solve.
Tap for more steps…
Set the first factor equal to 0.
n+5=0
Subtract 5 from both sides of the equation.
n=-5
n=-5
Set the next factor equal to 0 and solve.
Tap for more steps…
Set the next factor equal to 0.
n+15=0
Subtract 15 from both sides of the equation.
n=-15
n=-15
The final solution is all the values that make (n+5)(n+15)=0 true.
n=-5,-15
