Solve the radical equation square root 25-40x=x-10

15 or - 5

Step-by-step explanation:

√ (25-40x) = x-10

Squaring both sides

25 - 40x = (x - 10) ²

25 - 40x = x² - 20x + 100

x² - 20x + 40x + 100 - 25 = 0

x² + 20x = - 75

x² + 20x + 10² = - 75 + 100

(x + 10) ² = 25

x - 10 = ±√25

x - 10 = ±5

x = ±5 + 10

x = 15 or x = - 5
