Given:
The equation is
[tex]9x^2-12x+4=49[/tex]
To find:
The equation after first step to solve the given equation by using square root property.
Solution:
We have,
[tex]9x^2-12x+4=49[/tex]
It can be written as
[tex](3x)^2-2(3x)(2)+(2)^2=49[/tex]
[tex](3x-2)^2=49[/tex] [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]
Therefore, the equation can be rewritten in first step as [tex](3x-2)^2=49[/tex].
