Answer :
Answer:
See answer below
Step-by-step explanation:
x² - 10x + 30 = 0
x² - 10x = -30
x² - 10x + 25 = -30 +25 1/2 of the x term and square that number and add to
both side.
x² -10x + 25 = -5
(x - 5)(x - 5) = -5
[tex]\sqrt{(x-5)(x-5)^2}[/tex] = [tex]\sqrt{-5}[/tex]
If you are in Algebra II , then the answer is not a real answer it will be
(x - 5)² = ±5i
