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 -18 and whose sum is 3.
-3,6
Write the factored form using these integers.
(n-3)(n+6)=0
(n-3)(n+6)=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-3=0
n+6=0
Set the first factor equal to 0 and solve.
Tap for more steps…
Set the first factor equal to 0.
n-3=0
Add 3 to both sides of the equation.
n=3
n=3
Set the next factor equal to 0 and solve.
Tap for more steps…
Set the next factor equal to 0.
n+6=0
Subtract 6 from both sides of the equation.
n=-6
n=-6
The final solution is all the values that make (n-3)(n+6)=0 true.
n=3,-6
Solve for n n^2+3n-18=0
