Question

2 (x-5)^2-50=0 essa eu quero ver​

Answer 1

2.(x - 5)² - 50 = 0

2.(x² - 2.x.5 + 5²) - 50 = 0

2.(x² - 10x + 25) - 50 = 0

2x² - 20x + 50 - 50 = 0

2x² - 20x = 0

2x.(x - 10) = 0

x' = 0

x - 10 = 0

x = 10

S = {0, 10}

Answer 2

2(x-5)^2-50=0

2(x-5)^2 = 50

(x-5)² = 25

(x-5) = √25

(x-5) = ± 5

=> x-5 = +5 => x'= 5+5= 10 ✓

=> x-5 = -5 => x"= -5+5= 0 ✓
