How do you solve #k^2+6=6#?

Answer 1

Ethan Adkins

#color(green)(k=0)#

Given #k^2+6=6#

After subtracting #6# from both sides: #k^2=0#

Taking the square root of both sides: #k = +-sqrt(0) =0#

To solve the equation (k^2 + 6 = 6), you need to isolate the variable (k). Subtract 6 from both sides of the equation: [ k^2 + 6 - 6 = 6 - 6 ] [ k^2 = 0 ] Take the square root of both sides: [ \sqrt{k^2} = \sqrt{0} ] [ k = 0 ] So, the solution to the equation is ( k = 0 ).
