Answer:
x = (1/2) (-9 ± √73)
Step-by-step explanation:
Using completing the square method
x²+9x+2=0
x²+9x = -2 (complete the square by adding (9/2)² to both sides)
x²+9x + (9/2)² = -2 + (9/2)²
( x + (9/2) )² = -2+ (9/2)²
( x + (9/2) )² = -2+ (81/4)
( x + (9/2) )² = 73/4
x + (9/2) = ± √(73/4)
x + (9/2) = ± √(73) / 2
x = -(9/2) ± √(73) / 2 (factorize out (1/2) )
x = (1/2) (-9 ± √73)
The answer is 9y^2x(the 2 goes on top were the arrow is ) Hope this was helpful!
We know that
the capacity of container is 1 quart--------> 0.25 gallon------> 1/4 gallon
so
1/4 gallon-----------------> 1 time
5 gallons----------------> X times?
X=5/(1/4)--------> X=20 times
the answer is
20 times
