9-(r+2t)(r+2t)=0

Solution for 9-(r+2t)(r+2t)=0 equation:

Simplifying
9 + -1(r + 2t)(r + 2t) = 0

Multiply (r + 2t) * (r + 2t)
9 + -1(r(r + 2t) + 2t * (r + 2t)) = 0
9 + -1((r * r + 2t * r) + 2t * (r + 2t)) = 0

Reorder the terms:
9 + -1((2rt + r2) + 2t * (r + 2t)) = 0
9 + -1((2rt + r2) + 2t * (r + 2t)) = 0
9 + -1(2rt + r2 + (r * 2t + 2t * 2t)) = 0
9 + -1(2rt + r2 + (2rt + 4t2)) = 0

Reorder the terms:
9 + -1(2rt + 2rt + r2 + 4t2) = 0

Combine like terms: 2rt + 2rt = 4rt
9 + -1(4rt + r2 + 4t2) = 0
9 + (4rt * -1 + r2 * -1 + 4t2 * -1) = 0
9 + (-4rt + -1r2 + -4t2) = 0

Solving
9 + -4rt + -1r2 + -4t2 = 0

Solving for variable 'r'.
