Solve for x = ______?
\(x^2+10x+9=0\)
-1 or -9
2 or 1
8 or 3
7 or -2
Detailed Explanation
Factor the quadratic equation: \(x^2+10x+9=0\)
\((x+1)(x+9)=0\)
For this expression to be true, the left side of the expression must equal zero. Therefore, either (x + 1) or (x + 9) must equal zero:
If (x + 1) = 0, x must equal -1
If (x + 9) = 0, x must equal -9
So the solution is that x = -1 or -9.
