Solve this quadratic equation by completing the square x^2-8x+10=0

x = 4 ±

Step-by-step explanation:

Given

x² - 8x + 10 = 0 ( subtract 10 from both sides )

x² - 8x = - 10

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + 16 = - 10 + 16

(x - 4)² = 6 ( take the square root of both sides )

x - 4 = ± ( add 4 to both sides )

x = 4 ± ← exact solutions

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
