Answer:
x = 5 and x = - 5
Step-by-step explanation:
Given
x² - 25 = 0 ← x² - 25 is a difference of squares and factors as
(x - 5)(x + 5) = 0
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 5 = 0 ⇒ x = - 5
8 times y divided by 3
3 divided by 8 times y
3 times y divided by 8
3 times y divided by 8
(the last answer)
Because "3y" comes first and then "÷ 8" so the order is correct with 3 times y divided by 8, and the others can be ruled out.
