solvefor r,A=pi(r^2-r^2)

solve for

r, A = π (r^{2} - r^{2})

True for all r; 0 = \frac{A}{π}

Solution steps

A = π (r^{2} - r^{2})

Switch sides

π (r^{2} - r^{2}) = A

Divide both sides by

π

\frac{π ( r ^{2} - r ^{2} )}{π} = \frac{A}{π}

Simplify

0 = \frac{A}{π}

Both sides are equal

True for all r; 0 = \frac{A}{π}

x^{2} - 12 x - 10 = 0

5 x^{2} + 24 x = 0

(x - 5)^{2} - 10 (x - 5) = 24

\frac{7 x ^{2}}{2} = 27.7778

4 (x^{2} + x - 2) = x + 2
