Question

Find the roots of x²-6x+5=0 by using completing square method.

Answer 1

Answer:

x2-5x-x+5=0

x(x-5)-1(x-5)=0

(x-1)(x-5)=0

x=1, x=5 ans

Answer 2

Answer:

Step-by-step explanation:

$(x-3)^{2} +5-9=0\\(x-3)^{2}=4\\x-3=\sqrt{4} \\x= 3-2=1\\or \\x=3+2=5$

therefore, roots of the equation are, x=1 or x=5
