Question

solve the equation using formula :x²-6x+8=0​

Answer 1

Answer:

Step-by-step explanation:

x^2-6x+8

x^2-4x-2x+8

x(x-4)-2(x-4)=0

x-2=0       and              x-4=0

therefore x=2,4

Answer 2

Answer:

x^2-6x+8 = 0

by middle term splitting

x^2-4x-2x+8

x(x-4) -2(x-4)

= (x-2)(x-4) = 0

one of term should become zero to make this equation possible.

x-2 = 0

x = 2

x-4 = 0

x = 4

therefore x= 2,4.
