Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x2 + 3 = 9x a 0.35, -8.65 b -0.35, -8.65 c -0.35, 8.65 d 0.35, 8.65

1. You have the following quadratic equation and to solve it, you must follow the steps below:
 
 x²+3=9x
 
 2. The form of the equation that you need to apply the quadratic formula, is:
 
 ax²+bx+c=0
 
 3. Then:
 
 x²+3=9x
 x²-9x+3=0
 
 4. The quadratic formula is shown below:
 
 x=(-b±√(b^2-4ac))/2a
 
 5. Then, you have:
 
 a=1
 b=-9
 c=3
 
 6. When you substitute the values into the quadratic formula, you obtain:
 
 x1=0.34
 x2=8.65

No he does not because he can only cover 12 square feet from 15 square feet which he will still need 3 more. this is because if 3×5=15 square feet and 15-12=3 which thats the answer
