Complete the square (x2 + 4x + 2 = 0)
x = (y+2)2 - 2
y = (x+2)2 - 2
y = (x+2)2 + 2
y = (x+4)2 - 0
Bob decided to have a car wash. He charged $10 for cars and $20 for trucks and SUV's. 24 people came to his carwash in 4 hours. He made a total of $240. How many cars came and how many trucks and SUV's came?
Cars = 12 / Trucks and SUV's = 6
Cars = 5 / Trucks and SUV's = 10
Cars = 2 / Trucks and SUV's = 12
Cars = 4 / Trucks and SUV's = 8

Solve using completing the square (x2 + 28x +52 = 0)
(x+14)2 = 2903
(x+14)2 -144 = 0
(x+14)2 = 144
(x+14)2 - 1.44 = 0
Solve using zero product property (4x2 + 8x - 60 = 0)
x = 80 or x = 5
x = 3 or x = 5
x = -3 or x = 5
x = 3 or x = -5
