Solution
-\left(4x+9\right)
Show Solutions
Find the roots
x=-\frac{9}{4}
Alternative Form
x=-2.25
Evaluate
-4x-9
To find the roots of the expression,set the expression equal to 0
-4x-9=0
Move the constant to the right-hand side and change its sign
-4x=0+9
Removing 0 doesn't change the value,so remove it from the expression
-4x=9
Change the signs on both sides of the equation
4x=-9
Divide both sides
\frac{4x}{4}=\frac{-9}{4}
Divide the numbers
x=\frac{-9}{4}
Solution
x=-\frac{9}{4}
Alternative Form
x=-2.25
