7r²+9=1
the equation is contradictory, just to prove
7r ² + 9 = 1
7r² + 9 - 1 = 0
7r² + 8 = 0
We write the equation in the form of products of
7 * (r² + 8/7) = 0
the product is equal to 0 when one of the factors is zero
7≠0 ∨ (r² + 8/7) = 0
r² ≠ - 8/7
any number squared is not negative.
We proved that none of the factors is not equal to zero, so the right side of the equation is not equal to the left. The equation is contradictory
