Question

x^2-10x=-25

Answer 1

\(x^2-10x=-25\\ \Leftrightarrow x^2-10x+25=0\\ \Leftrightarrow\left(x-5\right)^2=0\\ \Leftrightarrow x-5=0\\ \Leftrightarrow x=5\\ Vậy\text{ }x=5\)

Answer 2

\(x^2-10x+25=0\)

\(\left(x-5\right)^2=0\)

x=5

Answer 3

x² - 10x = - 25
=> x² - 10x + 25 = 0
=> ( x - 5 )² = 0
=> x - 5 = 0
=> x = 5
Vậy x =5

Answer 4

x²-10x=-25

=>x²-10x+25=0

=>(x-5)²=0

=>x-5=0

=>x=5
