hope this help Answer:( x - 3i√2)(x + 3i√2)
solve x² + 18 = 0
x² = - 18 ⇒ x = ±√- 18 = ±3i√2
factors are ( x - (3i√2))(x - (-3i√2))
x² + 18 = (x - 3i√2)(x + 3i√2
Step-by-step explanation:
33 minutes because 56 plus 10 equals 66 divided by 2 equals 33
The answer is 1.
Side 5 and x^2+4x are the same length, so you can plug in the answer choices until the equation equals 5.
