Answer:
x=0, x= -9
Step-by-step explanation:
First we simplify the equation into the form
ax^{2}+bx+c=0
By adding 4x+3 on both sides, we form the equation
x^{2}+9x=0
Now, we factor out the common factor: x.
x(x+9)=0
The only values that allow x(x+9) to be equal to 0 are:
x=0 or
x+9=0
The solutions are x=0 or x= -9
