What is the answer to x^2-11=25 please

Hey there!

x^2 - 11 = 25

ADD 12 to BOTH SIDES

x^2 - 11 + 11 = 25 + 11

CANCEL out: -11 + 11 because that gives you 0

KEEP: 25 + 11 because that helps solve for the x-value

25 + 11 = 36

NEW EQUATION: x^2 = 36

Take the square root of the number (36)

x = ± √36

± = plus or minus

x = √-36 = -6

or

x = √36 = 6

x = 6 or x = -6

Good luck on your assignment and enjoy your day!
