x² + 4x + 4 = 18

x=−4±32‾√
x=2±32‾√
x=−2±32‾√
x=4±92‾√

x=−2+3√2

Step-by-step explanation:

x2+4x+4−18=18−18

x2+4x−14=0

For this equation: a=1, b=4, c=-14

1x2+4x+−14=0

x=

−b±√b2−4ac

2a

x=

−(4)±√(4)2−4(1)(−14)

x=

−4±√72

x=−2+3√2 or x=−2−3√2

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.
