Question

Tìm x:\(\left(x-5\right)^2=5^2\)

Answer 1

=> x-5=5

=> x=5+5

=> x=10

Answer 2

(x - 5)² = 5²

=> x² - 5² = 25

=> x² - 25 = 25

=> x² = 25 + 25

=> x² = 50

=> x = \(\sqrt{50}\)

Answer 3

\(\left(x-5\right)^2=5^2\)

\(\Rightarrow x^2-10x+25=25\)

\(\Rightarrow x^2-10x=0\)

\(\Rightarrow x\left(x-10\right)=0\)

\(\Rightarrow\orbr{\begin{cases}x=0\\x-10=0\end{cases}\Rightarrow\orbr{\begin{cases}x=0\\x=10\end{cases}}}\)

Answer 4

C2 : \(\left(x-5\right)^2=5^2\)

\(\Rightarrow x-5=5\)

\(\Rightarrow x=5+5\)

\(\Rightarrow x=10\)

Answer 5

\(\left(x-5\right)^2=5^2\)

\(\Rightarrow x-5=5\)

\(\Rightarrow x=5+5\)

\(\Rightarrow x=10\)

k nha

Answer 6

(x-5)^2=5^2

x-5=5

x=0

Answer 7

(x-5)^2=5^2

x-5=5

x=10
