Answer:
x = 3/5, -3/5
Step-by-step explanation:
Answer:
x = ± 
Step-by-step explanation:
Given
25x² + 1 = 10 ← subtract 10 from both sides
25x² - 9 = 0 ← in standard form
note that 25x² - 9 is a difference of squares and factors as
(5x - 3)(5x + 3) = 0
Equate each factor to zero and solve for x
5x - 3 = 0 ⇒ 5x = 3 ⇒ x =
5x + 3 = 0 ⇒ 5x = - 3 ⇒ x = -

Answer:
x = -25 / 3
Step-by-step explanation:
10 / 3 = x / (-5/2)
10 / 3 * (-5 / 2) = x
x = -50 / 6
x = -25 / 3
