Question

METAL square root r^2+49=49

Answer 1

Simplifying
r2 + 49 = 49

Reorder the terms:
49 + r2 = 49

Add '-49' to each side of the equation.
49 + -49 + r2 = 49 + -49

Combine like terms: 49 + -49 = 0
0 + r2 = 49 + -49
r2 = 49 + -49

Combine like terms: 49 + -49 = 0
r2 = 0

Solving
r2 = 0

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Simplifying
r2 = 0

Take the square root of each side:
r = {0}
